ABC News reports that former Massachusetts governor Mitt Romney won the Iowa caucuses by only 8 votes.
Rick Santorum attracted many evangelical Christians and social conservatives, coming in second. Rep. Ron Paul came in third with 21% of the vote.
Former Speaker of the House Newt Gingrich, still bitter over the negative campaigning from the Romney camp that knocked him from the top tier of presidential candidates, finished in fourth place.
Gov. Rick Perry announced his intention to go back to Texas, saying, "I've decided to return to Texas to assess the results of tonight's caucus, determine whether there is a path forward for myself in this race." In other words, he may be dropping out of the competition soon.
UPDATE: Also from ABC News: Rep. Michele Bachmann will not be going to South Carolina, after all. After her poor showing in Iowa, she has decided to drop out of the presidential race.
