The exclusion of Newt Gingrich from Virginia's presidential primary is heightening scrutiny of his campaign organization and the state's strict rules for ballot access.
The Republican Party of Virginia announced at 2:40 a.m. Saturday that Gingrich, like Texas Gov. Rick Perry, had failed to amass the required 10,000 signatures of registered voters to get on the ballot for the March 6 primary. Former Massachusetts Gov. Mitt Romney and Texas Rep. Ron Paul are the only candidates whose names will appear on the ballot.
