Alternate Mormon Kennedys

I didn't finish my thread. the kennedys become LDS in Ireland and immigrate to California then Utah how would this shape American History differently?
 
If they are still Democrats, we could have Bobby vs Romney, sr in 68! No chappaquick, since folks without ice tea, aren’t going to drink.
 
There's a huge amount of potential butterflies here, but I'll try to keep it concise. Assuming that the Kennedy political dynasty still comes into existence, it probably doesn't look the same as it does today in many respects. As a matter of fact, John F. Kennedy as we know him probably isn't the same person, quite literally. His grandfather, P.J. Kennedy met his grandmother in Boston. So if we assume that the question here is "What happens to the US without the Kennedy family?", that makes it a bit easier to answer.

Joe Kennedy, JFK's father, probably never exists either (or, again, is a totally different person, same in name only). Which means he's never SEC Chairman under President Franklin Roosevelt, and never the Ambassador to the United Kingdom in 1938. Joe Kennedy believed that we could compromise with Adolf Hitler, and held out on that belief for a while. That belief, combined with his eventual comment that Democracy was "finished" in England, and potentially in the US, diminished what previous political influence he had. Without him, maybe we enter World War 2 earlier, but I'm doubtful on that point. On the whole, no Joe Kennedy mostly has impact on the financial world, but I have to imagine another ruthless businessman would fill his shoes.

No JFK is a bit more significant. The 1960 Democratic Nominee might be Hubert Humphrey, or Lyndon B. Johnson instead (or perhaps some combination thereof). Could one of these two beat Nixon? Possibly, but given how close the election was IOTL, and how uninspiring these two are (at least compared to JFK), I might give it to Nixon. I don't think either of these men would do as well in the televised debates as JFK did, nor do I think either (especially Johnson) would have the same huge support of African-Americans. The Democratic Party looks different as a result, though what direction it goes in is hard to say. But for sure, they lose out on a number of liberal icons. Without the Southern Strategy on part of Nixon, the traditional party lines remain intact for at least a bit longer. How much longer though, i'm not sure.
 
With Butterfly effects in mind I want to give this a try:
PJ Kennedy the son of Irish immigrants in Boston comes across The Book of Mormon and meets LDS missionaries. PJ fascinated with the Gold plates makes the trip to Palmyra NY and is convinced the LDS church is true. In this timeline PJ moves to Utah before he meets his wife like in our timeline. PJ upon arrival to Deseret groups up with other New England LDS refugees. He meets a woman named Sarah Tingey. PJ amd Sarah are soon married and pregnant with their son Joseph Kennedy. PJ becomes involved with local politics around Salt Lake amd church activities amd becomes friends with prominent mormons. PJ and through charm was able to become president of the University of Utah in 1893. After serving as President of the Universoty. PJ invests in several smart investments in California amd Utah including becoming a board member for Zions bank. Pj pushing for statehood instead of keeping Polygamy made him unpopular to some but PJ eventually was able to narrowly win a state senate seat in the 1890s. Joseph Kennedy was enrolled in what would later become Brigham Young University. Joseph aspiring for more becomes a lawyer and becomes a power broker in Los Angeles becoming a major player in Hollywood. In this timeline Joseph while looking to invest in cattle meets Teddy Roosevelt in the Bad lands. Roosevelt amd Kennedy become a poloitical force not to be trifled with. Joseph becomes vital in making the national parks for Roosevelt amd even with the graces of Roosevelt becomes a founding member of the Securities and exchange commission. Joseph in this timeline has children by the same names like in our timeline but JFK wanting to be different goes to Stanford University and major in History amd later goes to law school at University of California hasting College of law. JFK serves in the military but he serves in the US senate pushed by Joseph Kennedy. JFK while playing around Beverly Hills met his future wife Veronica Lake. Elected in 1960 like in our timeline Veronica Lake is suffering with alcoholism just like in our timeline making headlines over her being the drunken First Lady even falling drunk at his celebration party after his 1960 win. With News circulating that JFK was sleeping with Marilyn Monroe Veronica Lake overdoses on heroine and other drugs and drowns in a White House bathtub . distraught over his wife's death and blaming himself privately, JFK cancelled his Dallas trip November 22, 1963. Lee Harvey Oswald is arrested for suspicious activity amd the story makes front page news. JFK wanting to take a vacation goes to Cape Cod instead of his family compound in California. In Cape Cod JFK meets Jackie Bouvier and they fall in love. JFK amd Bouvier are married in 1964 and they have three sons one of them JFK Jr is born in 1965. JFK amd JR develop a deep bond and Joseph Kennedy and JR become devout LDS. Bouvier raises the children LDS but introduces her children to some ideas of Catholicism. JFK's children from his marriage to Lake are loved by Jackie but two of his sons Charles Kennedy and Michael Kennedy are showing signs of alcoholism and drug dependency from their time as teens at private school in DC. Michael amd Charles become the black sheep of the family but Charles has a politicians charisma, an athletes body and the tact of a chess player. Joseph concerned about Michael and Charles invites LDS apostles amd prophets to come speak and pray and advise them. This puts them on the right track with Michael and Charles going to BYU. JFK JR amd the other children of Jackie and JFK along with their step children spend alpt of time between Utah, California, New England amd NY. Michael and Charles in Utah marry nice girls who are Jackie approved as JFK would say. Michael would later become a US Senator for California while Charles became a Congressman for Colorado then a Supreme Court justice. In this timeline Patrick Bouvier Kennedy does not die. His career i politics started with him in the DAs office then he became Governor of Massachusetts. JFK JR. In this timeline doesn't fly like he did in this timeline becomes president of the US in 2008. JFK never forgave himself for Robert Kennedy being assasinated in 1968. He always felt that his brother was trying to shadow him. Jackie noted to presidential historians how hard JFK took RFKs death. After JFK served his 8 years Jackie told reporters that she wanted to stay in DC for her children and step children's education. Rumours circulated in 1968 That JFK was eying buying a compound outside DC in Virginia. Just like in our timeline Joseph invested heavily in real estate but in this timeline it was in California, Utah, Colorado ,New York, Illinois, and Massachusetts. The Kennedy real estate holding company owned significant shares in Vail Colorado, Aspen Colorado, amd Park City Utah netting the Kennedy fortune and trust an impressive 10 billion
