WASHINGTON -- Former Sen. Rick Santorum, who shocked the political world by emerging from the back of the Republican presidential pack to pose a formidable challenge to former Massachusetts Gov. Mitt Romney, suspended his campaign Tuesday.
Santorum's announcement in Gettysburg, Pa., effectively ends the Republican presidential primary season with Romney holding a sizable lead in delegates over Santorum, a former two-term Pennsylvania senator, former House Speaker Newt Gingrich, and Rep. Ron Paul.
"We made a decision to get into this race at our kitchen table against all the odds, and we made a decision over the weekend that, while this presidential race is over for me and we will suspend our campaign today, we are not done fighting," Santorum said.
