WASHINGTON – Mitch McConnell, the Senate's most powerful Republican, will get his first big 2014 electoral test Tuesday as he faces a Tea Party challenger who's trying to mobilize anti-incumbent sentiment.
Kentucky's GOP primary is the main attraction, when six states will provide the biggest day of tests yet for the Republican establishment and the grass-roots Tea Party, which has roiled the party.
Two other states will be closely watched for clues about who's winning the struggle. In Georgia, three incumbent congressmen are vying with two Washington outsiders for the party's Senate nomination. In Idaho, veteran Rep. Mike Simpson is battling Tea Party favorite Bryan Smith.
Underscoring all of it is a strong anti-insider mood. And no one on the ballot Tuesday symbolizes insider Washington like McConnell, who's seeking his sixth term in the Senate.
McConnell is being challenged in the primary by Louisville businessman Matt Bevin. Even if Bevin loses — and he's far behind in a recent poll — a strong showing by the challenger would signal that McConnell is in for big trouble in the general election against likely Democratic nominee Alison Lundergan Grimes.
People are thinking that, " 'If we hate Washington, if we hate Congress, if we hate what's going on and you're one of the most powerful people in Congress, we must hate you more [than] anybody else,' " said political analyst Charlie Cook.
Establishment candidates have rebounded so far this year. They've been ready for the Tea Party challenges. In many cases, insurgents have proved to be poor candidates or unable to mobilize the same passion that boosted the Tea Party when it became a political force in 2010.
Turnout in state after state is expected to be very low, meaning the nontraditional grass-roots voters that the Tea Party attracts are more likely to stay home, said Matt Towery, chief executive officer of Atlanta-based InsiderAdvantage, a political media and polling firm. "We don't expect the same degree of impassioned voting this year," he said.
