(CNN) – The election is still more than a year away, but Sen. Mitch McConnell's campaign coffers got a boost Monday when fellow Republican Sen. Marco Rubio helped rake in more than $230,000 at a fundraiser in Kentucky.
At the event, Rubio praised McConnell, the Republican leader in the Senate, for his drive in pushing forward the GOP agenda in the upper chamber.
"Mitch McConnell's quiet, principled leadership is key to everything we accomplish on Capitol Hill," Rubio said at the fundraising event. "The way he fought Obamacare, tooth and nail, and forced the Democrats to use extraordinary measures to pass it was a critical catalyst in electing my entire class of Senate conservatives in 2010. Without Mitch, I don't know that we'd have Senator Rubio, Senator Johnson, Senator Paul or Senator Lee."
Those names were all elected to the Senate with support from the tea party, whose members have sometimes viewed McConnell skeptically. No Republican candidate has emerged thus far that would challenge McConnell in a primary contest in 2014.
One potential Democratic rival is actress Ashley Judd, though she has yet to formally jump in the race. McConnell's team has already gone after her in a web video for living in Tennessee rather than Kentucky.
In all, McConnell's campaign had $7.3 million cash on hand as of their last filing with the Federal Election Commission.
Earlier, Rubio spoke at the University of Louisville's McConnell Center, named after the senator. Introducing Rubio, McConnell joked about the Florida Republican's own political future.
"He's starting to look at vacation homes in Iowa and New Hampshire," McConnell quipped.
