As one conservative intellectual said to me - he said if the choice is between [Joseph] Stalin and [Adolf] Hitler, I'd pick Stalin, meaning Ted Cruz because he's more predictable. So there's real civil war inside the Republican Party.
Mara LiassonYou have [Donald] Trump and [Ted] Cruz battling it out, and the moderate establishment candidates like Chris Christie or Jeb Bush, Marco Rubio, John Kasich - they have formed a circular firing squad.
Mara LiassonI think that's why we see this mixed reaction - Republican congressional leaders like Paul Ryan speaking out very firmly, but Republican candidates not as much, with the exception of the candidates in the single digits like Jeb Bush or Lindsey Graham, who said how to make America great again tell - Donald Trump to go to hell.
Mara LiassonSenate races have tightened along with the presidential race. Watch to see how many Republican Senate candidates outperform Donald Trump - and how many hang on to their seats in states that he loses.
