4 months to the California Primary, but fresh after caucus wins in Colorado and Minnesota and in Missouri's non-binding primary, Rick Santorum draws to within a whisker of nominal frontrunner Mitt Romney, 33% for Romney, 31% for Santorum, effectively even, according to a SurveyUSA poll conducted for KABC-TV Los Angeles, KPIX-TV San Francisco, KGTV-TV San Diego and KFSN-TV Fresno. Santorum leads Romney among seniors, among evangelicals, among pro-life voters, among Tea Party members, among those who say they are "very conservative," and in the Central Valley region of California.
