From The Fix by Chris Cillizza:
In the Democratic primary, Colbert takes 2.3 percent of the vote — good for fifth place behind Sen. Hillary Rodham Clinton (40 percent), Sen. Barack Obama (19 percent), former Sen. John Edwards (12 percent) and Sen. Joe Biden (2.7 percent. Colbert finished ahead of Gov. Bill Richardson (2.1 percent), Rep. Dennis Kucinich (2.1 percent) and former Sen. Mike Gravel (less than 1 percent).
He was less lucky in the Republican field, where he took less than 1 percent of the vote behind even longshot candidates like Reps. Tom Tancredo and Ron Paul. Former New York City Mayor Rudy Giuliani led the Republican field with 29 percent, followed by former Gov. Mitt Romney at 12 percent, former Sen. Fred Thompson (11 percent) and Sen. John McCain (10 percent).
