Ted Cruz Wins Iowa Republican Caucus

Clinton and Sanders Too Close to Call

On "The Kelly File" tonight, Charles Krauthammer said that the Iowa caucus was a major inflection point on the Republican presidential campaign, as it punctured the aura of invincibility surrounding Donald Trump.

"Had Trump won, it would have reinforced the sense of inevitability, the momentum he had," Krauthammer explained. "This is the first time he's encountered defeat."

Krauthammer said this will have an effect on the voters who have been swept up in Trump's momentum and, more importantly, on the media, who will likely no longer feel the need to cover every single thing Trump says or does.

"There's going to be a lot of attention now to what Cruz is saying and Rubio is saying," Krauthammer said. "This is now a three-man race."

He explained that Cruz represents the more serious, austere conservatives, Trump appeals to voters with a more populist message, and Rubio is the more mainstream, moderate candidate.

Krauthammer added that Trump could still win the Republican nomination, but it's going to be a "long slog" and he's now guaranteed not to run the table.
