The LBJ/RFK fight was not the direct cause of the Democrats' loss in 1968. It did cause LBJ's withdrawal. "And then the thing that I feared most from the first day of my presidency had come true. Robert Kennedy had openly announced his intention to reclaim the throne in the memory of his brother. And the American people, swayed by the magic of the name, were dancing in the streets." I believe that, even though he could win renomination, he would lose to Nixon anyways. Though he believed that RFK or HHH were the vulnerable ones. We might see '72 avant l'heure in margins... As for Thatcher, who's "right" depends on your personal opinion. What is clear is that she lost the confidence of Cabinet by becoming too isolated, dogmatic, and intolerant of policy criticism. No killer instinct to compensate. Chretien/Martin was purely personal, though Martin was more of a fiscal conservative than Chretien. He wanted the throne before he got too old. RFK advocated New Politics, but he was in the Democratic ideological mainstream. Whether he was to the left or center of the Dems is a matter of opinion among authors and amateurs such as myself. About the GOP, they have long had their conservatives, moderates and RINO's such as Rockefeller. Nixon managed to unite them around his own centrist self in the 1960's. Were they a monolithic bloc? Not by a mile. They governed for 24 of 36 years between 1968 and 2004, and that is why I don't mention it. Did all of us Republicans love Reagan's domestic policies? No. But we most definitely did not like the alternatives on offer. The Dems and Tories, for a long time couldn't agree on fundamental questions such as Europe, the extent of the welfare state, etc. All the ones that I mentioned led to a loss of governance by the party involved. To take a Democratic example, Blue Dogs and Pelosi are both Democrats, but one's very liberal and the others are on the right of the Democratic Party. Every party has its wings.
One I forgot to mention as an example is what Indira Gandhi did to the Congress Party. Namely being hamstrung by the Syndicate, staging a fight over the state and party presidencies, turning the voters and backbenchers on them, and taking complete ideological and personal control by the 1971 election. Another example is Hawke and Keating in the 1990's? That looks quite interesting as well.
