A federal judge has refused to add Gov. Rick Perry and three other candidates to Virginia's Republican presidential primary ballot.
U.S. District Judge John Gibney ruled Friday that the candidates should have challenged Virginia's primary qualifying rules earlier. Gibney said they knew the rules months ago.
Perry sued last month after failing to submit enough signatures to get on the ballot. Newt Gingrich, Rick Santorum and Jon Huntsman also failed to qualify and later joined Perry's lawsuit. They asked Gibney to declare Virginia's law unconstitutional and add their names to the March 6 ballot.
Only Rep. Ron Paul who represents the 14th congressional district of Texas and former Massachusetts Gov. Mitt Romney qualified for the March 6 primary ballot.
