LAS VEGAS-Since PolitickerNV.com last reported on filing Monday evening, a large number of incumbents and a few new challengers have tossed their hats into the proverbial political ring.  Here's a brief rundown of those newly filed candidates.

Congressional District 1: Republican Kenneth Wegner has filed to challenge incumbent Democratic Rep. Shelley Berkley.  Wegner is the fifth Republican now to file along with Ray Kornfeld, Ed "Mr. Clean" Hamilton, Chris Dyer and Mike Powers.  Whichever Republican wins the primary will face a virtually insurmountable voter registration advantage for Berkley of more than 21 percent.

Rural Senate District: Incumbent Republican state Sen. Dean Rhoads has filed for reelection.
