MIAMI-DADE COUNTY, Fla. -

Mitt Romney was back on the campaign trail Monday.

The former presidential candidate is endorsing Carlos Curbelo in the Republican primary race for Florida's 26th Congressional seat -- a district where Romney failed to win the vote in the 2012 presidential race.

"I am here to do one thing and that is officially endorse Carlos for Congress," said Romney before a group of supporters at Vicky's Bakery.

Romney toured the family-run business and sampled a few desserts Monday.

The campaign stop comes as voters take to the polls in early voting. Curbelo, who is a school board member, is facing several other Republicans in next week's GOP primary.

The winner will face Democrat Rep. Joe Garcia in November.

"I think we deserve better," Curbelo said. "Gov. Romney knows we deserve better and with your support we will win this primary election next Tuesday and we will the general election."

A group of protestors organized by Democrats gathered outside the event.

Romney's decision to campaign for fellow Republicans in the coming months has led to speculation he would run for a third time in 2016.

"No, I'm not doing that," he said.

The remark drew laughter from the crowd, who gathered for the event.

"I'm delighted to be campaigning for someone else," Romney said. "It's easier and a lot less pressure."
