Campaign 2012: G... For many, the race to replace President Barack Obama seemed to start in January 2008.
Four long years later, the crowded field of Republican candidates chomping at the bit to replace Obama is finally thinning down to just one man (or two, Ron Paul! with Newt Gingrich stepping out of the race May 2.
Some candidates dropped out early, some offered impassioned Pokemon-themed goodbyes...some never actually said they were running at all, but still had to make official statements that they weren't in the race.
Hundreds of millions of dollars were raised and spent, but only one man is left leading the GOP field.
Here's a look at the long, and sometimes strange, race to the final 2012 showdown with incumbent President Obama.

Gingrich Makes i... Newt Gingrich can now call himself a former presidential candidate. As expected, the former house speaker has bowed out of the Republican presidential contest May 2 - just short of a year after getting into the race. He did not immediately endorse Mitt Romney, the likely GOP nominee. After losing contests in five states last week, Gingrich said it was clear that Romney would be the nominee and he signaled that his own topsy-turvy campaign had reached its end. Gingrich now has the added challenges of rebuilding his image as a one-man GOP idea machine and paying off at least $4.5 million in campaign debt. Joined by his wife for the announcement in Arlington, Va., Gingrich described the campaign as "an amazing year" for his entire family. (AP Photo)
