(NBC) -- The focus of the GOP presidential race today is on Colorado, Minnesota and Missouri.
All three hold contests on Tuesday.
Mitt Romney claimed a big win over the weekend in the Nevada caucuses, and even though his rivals insist the race isn't over yet, the former Massachusetts governor is gaining momentum.
"This is the state he won last time and he won it this time. Our goal is to get to Super Tuesday where we're in much more favorable territory," Newt Gingrich said after Romney's Utah win.
Gingrich and Ron Paul are hoping to rack up enough delegates to give Romney a fight.
Rick Santorum finished fourth in Nevada, he's hoping for a sudden game changer, but running out of time.
