No delegates were at stake on Tuesday night, but Rick Santorum still scored two big victories in the race for the Republican presidential nomination by winning Minnesota's caucuses and Missouri's primary.

"Conservatism is alive and well in Missouri and Minnesota," Santorum said when he took the stage at his victory party in St. Charles, Mo., calling his wins "a victory for the voices of our party, conservatives and tea party people, who are out there every day in the vineyards."
