For months, Santorum failed to raise money, failed to hire a campaign staff, failed to create a campaign structure, failed to create a base of supporters, and failed to impress in the endless stream of candidate debates. A couple of weeks before the Iowa caucuses, Santorum was in the low single-digits in national GOP polls -- he was neck and neck with Huntsman -- and was generally considered an afterthought, when he was considered at all.
And yet, despite having very little money, no staff, no organization, few endorsements, an unimpressive legislative record, and a weak message, Rick Santorum managed to beat Mitt Romney
10 times during the Republican nominating race (Iowa, Colorado, Minnesota, North Dakota, Oklahoma, Tennessee, Kansas, Alabama, Mississippi, and Louisiana). The total reaches 11 if you include Missouri's pseudo primary in February.
