WASHINGTON (WKOW)--There's speculation that none of the Republican presidential candidates will have enough delegates to clinch the nomination before this summer's convention.
It would be the first open convention since 1940.
Rick Santorum's three state sweep yesterday is what's creating the buzz.
He took momentum away from frontrunner Mitt Romney; and neither of the other two candidates, Ron Paul and Newt Gingrich, appear anywhere near giving up.
Overall, Romney has 107 delegates, Santorum is next with 69 delegates, followed by Gingrich with 32 and Paul with nine.
A candidate needs more than 1,100 delegates to win the GOP nomination.
