Observers have suggested that Virginia Republicans have several Democratic congressmen in their sights in November, but party squabbles could dash their hopes on Tuesday.

The Talking Points Memo Web site said that in the 5th Congressional District, conservative choice Laurence Verga has been losing some steam, and staffers as establishment favorite state Sen. Robert Hurt now is considered the likely winner. If Hurt emerges the winner, he would face incumbent freshman Rep. Tom Perriello.

However, several media outlets have reported that there could be some drama before November. He'll make a third-party run if Hunt bests the six other Republican candidates.

Clark told the Lynchburg News and Advance he considers Hurt as a "situational conservative."

While the district supported Republican presidential nominee John McCain in 2008, Perriello unseated Rep. Virgil Goode by a scant 727 votes of more than 315,000 tallies cast. His razor-thin margin is one reason why Republicans hope to reclaim the seat.

The Virginia Gazette in Williamsburg recently reported that in the 1st Congressional District, Tea Party activists aren't backing Republican Rep. Rob Wittman, considered a reliable conservative vote, in his re-election bid, throwing their support to Realtor Catherine Crabill instead.

Crabill doesn't represent too much of a threat and probably will garner votes only from Tea Party activists, some of whom have indicated they oppose Wittman because he's a "career politician," insiders have said.

The victor in the Republican primary will face Democrat Krystal Ball, a political neophyte who's running in one of Virginia's sturdiest Republican strongholds.

Pointing to Virginia's 2nd Congressional District, The Hill has reported recently that establishment candidates haven't done well so far this primary season, and political observers say they don't think Tuesday will be any different. (With Inputs from Agencies)
