Jon Huntsman will withdraw from the race tomorrow and endorse Mitt Romney:

Jon Huntsman will withdraw Monday from the race for the Republican presidential nomination, campaign officials told The Associated Press on Sunday.

Huntsman will endorse Mitt Romney at an event in South Carolina, the officials said. Huntsman believes Romney is the best candidate to beat President Barack Obama in November, they said.

In an interesting move, Huntsman already has turned “private” on YouTube his anti-Romney ads, which were devastating, such as Mittstant Replay (image via Elect Ad):

Update: Elect Ad is in the process of loading all the Huntsman ads to its own server to overcome the YouTube take down.  Mittstant Replay now is viewable.
