WASHINGTON — Republicans count enough competitive races to challenge Democrats for control of the Senate in the 2014 elections, if only they can figure out what to do with the tea party.
Crowded primaries in states such as Georgia, Iowa and North Carolina, where tea partyers and social conservatives are fighting for the nomination and pushing candidates farther right, worry many Republicans, especially after they saw their legitimate shots at a Senate majority slip away in 2010 and 2012.
Republicans need a net gain of six seats to capture control from Democrats, who effectively hold a 55-45 advantage now. But Democrats will be defending 21 of 35 seats to be decided in November, and President Barack Obama is looking like a major drag for them. Midterm elections are often tough for a president's party in any event.
"History is with us, geography is with us and the president's signature legislative achievement is the most unpopular" law of his tenure, Rob Collins, executive director of the National Republican Senatorial Committee, said of Obama and his health care overhaul.
Republicans inside and outside the Senate speak confidently about snatching open seats in West Virginia and South Dakota. They like their chances against Democratic incumbents in Republican-leaning Arkansas, Louisiana and Alaska and remain upbeat about Montana even if Democratic Gov. Steve Bullock names Lt. Gov. John Walsh to succeed Sen. Max Baucus, Obama's choice for U.S. ambassador to China.
The looming question is whether Republicans undercut their solid shot with tea party-style candidates who fizzled out in Delaware, Colorado and Nevada in 2010 and Indiana and Missouri in 2012.
Georgia is keeping some Republicans awake at night. Eight candidates, including three House members, are pursuing the open seat of retiring two-term Sen. Saxby Chambliss in a state that dramatically went Republican in 1994 and rarely has looked back. Georgia hasn't elected a non-incumbent Democrat since 1998.
