We have our first possible 2016 presidential candidate endorsement in the Georgia Republican U.S. Senate primary: Rick Santorum is backing Karen Handel.

Santorum was runner-up to Mitt Romney in the 2012 Republican presidential nomination and openly talking about a repeat bid. The former Pennsylvania U.S. Senator finished third in Georgia, his 19.6 percent of the vote trailing Newt Gingrich and Romney. While presidential hopefuls past and present took sides in North Carolina, they have not so far in Georgia.

Here's the full release:

Senator Santorum said, "I am pleased to announce our endorsement of Karen Handel for the U.S. Senate in Georgia.  She is a committed conservative who has an undisputed record of fighting for pro-life causes.   Karen will fight to repeal ObamaCare, cut spending and stop the heavy-handedness of the Obama Administration that is killing job creation in this country."

"Karen was a fiscal hawk in county government, balancing the budget and cutting wasteful spending.  And as Secretary of State, Karen became known for her efforts to make her office more transparent, something desperately needed in Washington, DC.  Karen's conservative views coupled with her ability to get things done will serve Georgia well in the U.S. Senate. I am pleased that Patriot Voices PAC is in her corner," Santorum concluded.
