Republican presidential candidate Newt Gingrich is committed to staying in the race, the former speaker of the House told CBS this morning:

Newt Gingrich has been battling calls for him to drop out of the Republican presidential race, after losing both the Mississippi and Alabama primaries Tuesday. But the former House Speaker said today his campaign will continue up to the party's convention in Tampa.

When asked by Charlie Rose under what circumstances he would end his campaign before the convention, Gingrich replied, "Probably none."

"I have 176,000 donors," he said. "Everywhere I went in Illinois yesterday, people came up to me and said, 'Please stay in the race, please represent big ideas, please represent things like $2.50 a gallon gas, a personal Social Security fund.'"
