The tide may be turning in Florida

The race in Florida may be changing again.

There are three robo-polls out today showing Romney back in the lead. NBC News does not endorse or report on automated polls.

But forget the polls, look at the rhetoric. Gingrich today leveled his harshest attacks yet on Romney in Florida after ignoring him at the NBC debate Monday night. If that suddenly rhetoric sharp rhetoric against Romney is any indicator, it may mean Romney’s regained the momentum.

Gingrich declared he was “angry” today. “I am angry," he said. "But I think I'm angry and every American should be angry.” He said of Romney, “How can somebody run a campaign this dishonest and think he's going to have any credibility running for president?”

He went on at a Tea Party rally: “This is the desperate last stand of the old order throwing the kitchen sink. I’m here as a citizen and I frankly don’t care what the Washington establishment thinks of me because I intend to change them.”

He charged that the ads are paid for “with the money taken from the people of Florida by companies like Goldman Sachs,” that are trying “to stop you from having a choice in this election.”

He added, in an attack he'd used in Iowa: “We aren't that stupid, and you aren't that clever.”

More evidence the tide may be turning. Romney's rhetoric on Gingrich was tame. And Romney mostly kept his focus on Obama, saying this is a "'Groundhog Day' presidency. … Nothing changes."
