Is Santorum Struggling?

Hello Readers and followers,
Today the talk of the country is the campaign theory. It is surprising that Rick Santorum has had success with a small staff, no infrastructure, little connection with the republican establishment, and lastly, very little money! The image up there describes how Rick (the bottom) has made an endless amount of stops in Iowa for the election while Mitt Romney (very top) spent little time in New Hampshire and Iowa where he was making an aggressive push, but Rick is still up there?
