Johnson wouldn't have got to the White House on his own.
Nixon didn't get there the first time and didn't last when he did.
Jimmy Carter only got there once - before people knew who he really was.
I hope Ted Cruz gets reelected, but he will never be president.
Personal unlikeability may not be the main reason, but it doesn't help him any.
You and I both know that Nixon won the 1960 election.
