GETTYSBURG, Pa. (AP) — Bowing to the inevitable after an improbably resilient run for the White House, Rick Santorum quit the presidential race Tuesday, clearing the way for Mitt Romney to claim the Republican nomination.“We made a decision over the weekend, that while this presidential race for us is over, for me, and we will suspend our campaign today, we are not done fighting,” he said.Santorum, appearing with his family, told supporters the battle to defeat President Barack Obama would go on but pointedly made no mention or endorsement of Romney, whom he had derided as an unworthy standard-bearer for the GOP.The former Pennsylvania senator stressed he’d taken his presidential bid farther than anyone expected, calling his campaign “as improbable as any race that you will ever see for president.”“Against all odds,” he said, “we won 11 states, millions of voters, millions of votes.”Santorum signaled his intent to maintain a voice in the campaign to come, saying: “This game is a long, long, long way from over. We will continue to go out and fight and defeat President Barack Obama.”Santorum spoke with Romney before the announcement, a Republican source close to the campaign said, and Romney asked to meet him sometime in the futureThe delegate totals told the tale of Santorum’s demise. Romney has more than twice as many delegates as Santorum and is on pace to reach the 1,144 delegates needed to clinch the nomination by early June.
