Santorum Raises $9 Million in February

WASHINGTON (AP) — Rick Santorum's presidential campaign raised $9 million in February as he emerged the chief rival to Republican Mitt Romney.

Santorum spokesman Hogan Gidley on Wednesday said more than 100,000 donors gave online to the former Pennsylvania senator. Gidley also said the campaign received more than 130,000 donations during the month that opened with surprising victories in Feb. 7's caucuses in Minnesota and Colorado and a nonbinding primary in Missouri.

Santorum continues to be outspent by Romney and his allies, but he mounted a strong challenge in Tuesday's primary in Romney's home state of Michigan.

Santorum now is looking ahead to next week's 10-state Super Tuesday and honing his message back to the economy and away from the social issues that marked his fast rise.
