Presumptive Republican presidential candidate Mitt Romney took his campaign to St. Petersburg this morning, addressing about 1,000 people at a public rally.

Speaking for about 25 minutes at the Mirror Lake Lyceum in St. Petersburg, Romney hit on most of his key themes, including reducing the national debt, shrinking the size of the federal government and repealing the Affordable Healthcare Act.

He spoke in front of a "debt clock" that purportedly displayed a real-time accounting of the national debt.

"He (president Obama) said he would cut the debt in half if he became president," Romney said. "Instead, he doubled it-he doubled it. ... This presidency has been a disappointment, and the people who have been hurt by this disappointment are the American people."

Romney also talked about building more Navy ships, increasing the military and doing more domestic drilling for oil. He spoke to a friendly crowd about 500 supporters.

"I think he spoke the truth. We don't need any more hope and change. At this point, I just hope it changes,” Maryann Gamrot, a Romney supporter.

Outside the rally, protesters held signs and chanted, "Mitt Romney kills jobs."

Members of Occupy St. Petersburg draped a red shoot over themselves. As Romney supporters walked by, they shouted, "Go ahead! Walk on the 99 percent!"

Romney had another stop to make in the Bay area. He headed to the Avila Golf & Country Club in Tampa for a fundraiser.

This was Romney's first trip back to the Bay area since winning the Florida Primary.
