Despite less than expected results in recent GOP primaries, Republican presidential candidate Newt Gingrich said he's staying in the race until his party's national convention.

The former House speaker told CBS's "The Morning Show" there's little chance he will pull out of the race before the August RNC nomination in Tampa.

"I have 176,000 donors at Newt.org. They want me to stay in the race," Gingrich said.

When asked what circumstances would cause him to drop his bid for president, he responded "probably none."

Gingrich has only won two states so far: South Carolina and Georgia.

That puts him well behind former Massachusetts Gov. Mitt Romney and former Pennsylvania Sen. Rick Santorum in the delegate count.
