U.S. Senator Marco Rubio campaigned with candidate Connie Mack IV at Versailles Restaurant in Little Havana on Monday morning.
Rubio is not up for reelection this year, but is hoping Mack can replace Bill Nelson as the other senator from Florida.
"Senator Nelson has made a habit of saying one thing to you and doing another in Washington. I'm going to make sure it's the last term for Senator Nelson," said Mack.
In his political career, Mack has rarely lost an election. Margins have often been hugely in his favor -- one reason why Republicans recruited the former state legislator to try to unseat Nelson.
But recent polls have Mack down double digit to Nelson with just four weeks to go until election day.
Rubio hoped to change that by sipping coffee with Mack among a strong Cuban base of supporters in Little Havana.
"He's always been such a strong supporter of freedoms and liberty across the globe -- not just in Cuba but in places like Venezuela," said Rubio. "Connie Mack can do it."
"There's a lot of forces on the other side. They're energized but you know what, we're energized, too. It's a team effort and I know with your help, we'll be successful," said Mack.
Both will continue north with a stop planned for The Villages on Monday afternoon.
