Florida Congressman Connie Mack is planning to enter the Republican race for U.S. Senate, adding a big name to a contest that has lacked drama for months.
"Connie Mack is running for the U.S. Senate. He is making calls. He is assembling a team. And he will have more to announce about the run in the weeks ahead," said David James, a senior adviser.
Mack, R-Fort Myers, declined to enter the race this spring when two of his former colleagues from the Florida House, Adam Hasner and Mike Haridopolos, were running. But Haridopolos dropped out earlier this summer.
But this could be a tough race for Mack, who could be perceived as too moderate -- especially when it comes to immigration -- in a Republican primary.
Alberto Martinez, a Hasner adviser, said this via Twitter: "Game on."
