UNITED STATES -- The inauguration stage is literally being built. Whoever stands on it in January probably won't regret all that time in the Florida heat.

Trying to reboot his campaign after a tough week, Mitt Romney came to the sweltering state wielding a new zinger.

"The President today threw in the white flag of surrender again!” Romney said. “He said he can't change Washington from inside. He can only change it from outside. Well, we're going to give him that chance in November. He's going outside!"

Romney has also talked about the inability to change Washington from inside. Obama said the same thing moments before on Florida's other coast.

"I've learned some lessons over the last four years. And the most important lesson is that you can't change Washington from the inside. You can only change it from the outside. That's how I get elected," President Obama said.

Obama says that's also how he passed his health care law, ignoring that it also took his party's control of Congress.

Even with that advantage, Obama couldn't rehaul the nation's immigration laws, as he was repeatedly reminded at the Univision forum.

Obama said, "What I'll say is that - that I haven't gotten everything done that I wanted to get done and that's why I'm running for a second term because we still have more work to do."

Romney defended himself on immigration a day earlier. He has called for self-deportation of illegal immigrants.

There was also no mention of immigration in his rally. It was tailored for another key Florida bloc.

Romney said, "I hope the people of Florida understand this. He cut Medicare by $716 billion. And if I'm President of the United States, we're going to put that $716 billion back into Medicare, back into the care of our seniors."

Romney ignored the fact that his own running mate called for those same savings or that experts see the cuts as ensuring the program survives.
