Santorum Surge That Got Anoka County Boost Ends in Penn.

It's exactly nine weeks to the day since Minnesota, and particularly Anoka County, elevated Santorum's candidacy with a strong caucus straw-poll showing. The Santorum surge started with simultaneous wins on Feb. 7 in Minnesota, Missouri and Colorado.
