(USA TODAY) — New polls show Rick Santorum poised for a “big day” in today’s GOP presidential contests in Colorado, Minnesota and Missouri.

Bragging rights are the only thing at stake in the three states, which won’t award delegates to the Republican National Convention in Tampa until district and state conventions or caucuses later this year.

The surveys by Democratic-leaning Public Policy Polling show Santorum possibly headed for a victory tonight in Missouri, where he leads Mitt Romney, 45% to 32%. The former Pennsylvania senator is also leading Romney in Minnesota, 33% to 24%.
