From The Fix:

Former Nevada state Republican Party Chairwoman Sue Lowden will announce her bid to challenge Senate Majority Leader Harry Reid today, immediately becoming the highest-profile candidate in an increasingly crowded field hoping to unseat the Nevada Democrat.
“I feel strongly that it is time for Senator Reid to be accountable to the voters of Nevada,” said Lowden in an interview with the Fix. “He has forgotten about the people who elected him to be there.”
Lowden also said she was “pleasantly surprised” by polling that showed her leading Reid since she hadn’t been on a ballot of any kind in the state since 1996 when she lost her re-election race for the state Senate. (That showing has more to do with voters’ displeasure with Reid than it does their love of Lowden, however.)
Lowden joins state Sen. Mark Amodei and businessman Danny Tarkanian — among others — in a Republican race that has seen several favorites of the national party (including former Rep. Jon Porter and Rep. Dean Heller) pass on bids.
