The GOP field is dwindling, and like in nature, its survival of the fittest – and only the strongest will survive in this race.

Earlier today, Rick Perry made the announcement that his presidential campaign is over – making him the second candidate in a week to drop out of the race (Jon Huntsman left the race on Monday). Perry also made a point to endorse Newt Gingrich, one of the four remaining candidates in the race.

That leaves Gingrich, Mitt Romney, Rick Santorum and Ron Paul to duke it out on Saturday in the South Carolina primary. By Sunday, there may be another candidate we see drop out of the race.

While Romney may seem like the frontrunner, new news from Iowa shows that Santorum – and not Romney – was the actual winner of the caucus of their state by less than 40 votes. This may throw a wrench into what Romney saw as an initial victory, and may in fact boost Santorum moving into this Saturday.

Out of the remaining candidates, whom do you foresee winning? And who are rooting for to go against Obama in November? Keep up with our Cultural Barometer elections Meter graph for all the latest info in politics.
