There is a strong headwind this cycle for Republican this year in Nevada, where control of the Senate could be decided: Democrats are registering voters at a higher rate than in the last two presidential elections.
Jon Ralston, a Nevada political commentator and radio host, reported that Democrats increased their voter registration advantage over Republicans by a little more than 3,600 in the last two months, and just less than 70,000 overall.
In Clark County, which covers most of Las Vegas, Democrats continued to pad their lead by more than 13 percent in the county.
At this point in 2012, Democrats had a total lead of 36,000 registered voters that expanded to over 90,000 by Election Day, according to a report from Ralston two months ago.
President Barack Obama won the state by more than 12 points in 2012 and less than half of that in 2012.
Ralston said that this advantage "came despite the herculean efforts of the conservative registration outfit, Engage NV." He said that these new numbers "tell an ominous story for the GOP."
This is an advantage for Democrats in a state where Republicans hope they have a chance to flip a Senate seat their way. The race between Democrat Catherine Cortez Masto and Rep. Joe Heck to replace retiring Minority Leader Harry Reid is rated Tossup by Rothenberg-Gonzales Political Report/Roll Call.
