Google's current election map for Iowa

There are still two possible Republican presidential candidates who could emerge victorious in tonight's Iowa caucuses: former Pennsylvania Senator Rick Santorum and former Massachusetts Governor Mitt Romney.

While it's still unclear who the eventual winner will be, the two candidates are running neck and neck with 25% of the vote each, it is abundantly clear who the winners aren't.

NBC just projected that Congressman Ron Paul will finish in a strong third place, while the rest of the networks are projecting that Former Speaker Newt Gingrich will finish in fourth, Texas Governor Rick Perry in fifth place, and Congresswoman Michele Bachmann bringing up the rear in sixth. (Former Utah Governor Jon Huntsman, who did not choose to compete in the caucuses, will be finishing in 7th place.)

Overall, turnout is projected to be  lower than in 2008.
