All of a sudden, the Republican race for president is practically over. Rick Santorum's surprise decision to suspend his campaign Tuesday, removed Mitt Romney's most serious competitor from the GOP primary battle.

 

Santorum made the announcement in his home state of Pennsylvania. He didn't say exactly why he's getting out of the race, but he did mention his 3-year-old daughter Bella's health. She spent the weekend in the hospital with pneumonia.

But even as Santorum dropped out of the Republican presidential race, he promised to help his party win in November, saying, "This game is a long, long, long way from over. We're gonna continue to go out there to fight to make sure that we defeat President Barack Obama."
