Hey Guys,
After the American-Mexican War have the United States annex all of North-East Mexico, which was itself an ammendment put forward by Jefferson Davies in the Treaty of Guadalupe Hidalgo. How could you have the Senate support this annexation? As shown in the Representatives it appears that the Democrats support the leadership of the party, thus if the Democratic leaders supported the ammendment could we have this ammendment pass?
P.s. If you must or can think of a way of having this occur within the Gadsden Purchase go ahead and say, especially if it'd be easier.
