Mitt Romney, Ron Paul Avoid Ballot Blunders Made By Rival Candidates (PHOTOS)

Several of the Republican candidates for president have failed to get on the ballot in some primaries or failed to file full slates of delegates in others, limiting their ability to win delegates in those slates. The exceptions: former Massachusetts Gov. Mitt Romney and Texas Rep. Ron Paul.

"This is why you need a real-life, no-kidding-around campaign," said GOP strategist Rich Galen, a former aide to Newt Gingrich, according to the Associated Press. "All these guys who have been crowing that they found a new way to run for president, it's like saying I'm inventing a new airplane, and it has only one wing."
