GRETA VAN SUSTEREN (HOST):I see the rallies and they're big, and I see the poll numbers, and he’s slipping in the polls, but I wonder how many people receive a phone call from some stranger saying who’re going to vote for and everybody -- you probably don’t want to say, well, we’re going to vote for the guy who uses bad language, so they say something else. I'm not so sure how accurate these polls are. I guess that during the primary they give us some indication, but how many people, when they go behind the closed curtain, are they going to vote for Trump? 

KARL ROVE: Well, what you are suggesting, and I'm not saying it's not worth considering this, but you're assuming first of all, the polls are not reliable -- all of them -- and second of all, that a better test this is the size of the crowds he gets at his rallies, which are big and enthusiastic. But I would remind you in the closing days in the 1984 presidential campaign, Walter Mondale was drawing large and enthusiastic rallies as he went on to narrowly win one state. When George McGovern was in the final stages in the 1972 campaign against Richard Nixon, the crowds were unbelievably large and enthusiastic. In 1996, Bob Dole was actually drawing good crowds as he came down the closing stretch, but none of that mattered. None of that mattered at the end of the day. There's a difference between who shows up at a rally and who turns out to vote and right today I wouldn't be betting that all of those polls showing -- I wouldn't bet the Fox News poll is wrong that says he's ten points down.
