Mitt Romney's final Florida rally. (Philip Rucker -- The Washington Post via Instagram)

At a rally in Sanford, Fla., Mitt Romney's final event in the Sunshine State, the candidate struck the optimistic tone that has marked his campaign over the past month as he told the roaring crowd of supporters that a "better tomorrow" that awaits them after Nov. 6.

The enthusiam of the crowd -- which chanted "45! 45!" as the would-be-45th-president delivered his remarks -- appeared to energize Romney, as he took a detour from his prepared remarks and delivered an extended riff on what that post-Obama future might look like.

"Tomorrow, we begin a new tomorrow," he said. "Tomorrow, we begin a better tomorrow. This nation is going to begin to change for the better tomorrow. ... We can begin a better tomorrow tomorrow, and with the help of the people in Florida, that's exactly what's going to happen."
