Republican presidential candidate Rick Santorum is campaigning in New Hampshire after finishing a very close second in the Iowa caucuses. His success in the Hawkeye State was a surprise because Santorum was polling in the single digits there just a few weeks back.
For Santorum, surprising the political establishment is nothing new. Since he was first elected to Congress in 1990 — at 32 years old — Santorum has made a career out of being the underdog and usually winning.
