Even as he acknowledged that Mitt Romney is in charge of the Republican race for the White House, Newt Gingrich emerges from the Easter weekend ready to continue his campaign for the White House, still refusing to get out of the GOP nomination fight.

Interviewed on Fox News Sunday, Gingrich admitted that you have to be "realistic" about where he is in the delegate count compared to Romney.

"Given the size of his organization, the number of primaries he's won, he's far and away the most likely Republican nominee," Gingrich said, as the former House Speaker then vowed to back Romney if necessary.

"And if he does get to 1144 delegates I'll support him. I'll do everything I can this fall to help him defeat Obama. Because the primary goal of the Republican party has to be to defeat Barack Obama."

Delegate counts by both media organizations and the Republican Party have Gingrich far behind Romney, who sports a sizeable advantage over Rick Santorum as well.

The current Associated Press delegate numbers have Romney with 660, Santorum at 281, Gingrich at 135 and Ron Paul at 51.

The numbers for Gingrich and Paul haven't moved in recent weeks.

But that's not stopping Gingrich and his wife Callista, who have an active schedule set for this week:
