WASHINGTON - The Republicans' clear defeat in the budget-debt brawl has widened the rift between the Grand Old Party and the blossoming tea party movement that helped revive it.
Implored by House Speaker John Boehner to unite and "fight another day" against President Barack Obama and Democrats, Republicans instead intensified attacks on one another, an ominous sign in advance of more difficult policy fights and the 2014 midterm elections.
The tea party movement spawned by the passage of Obama's health care overhaul three years ago put the GOP back in charge of the House and in hot pursuit of the law's repeal. The effort hit a wall this month in the budget and debt fight, but tea partyers promised to keep up the effort.
In this Wednesday photo, Sen. Mike Lee, R-Utah, left, and Sen. Ted Cruz, R-Texas, walk to the Senate floor to vote on a bill to raise the debt ceiling and fund the government on Capitol Hill in Washington. The budget-debt brawl has widened the rift between the Grand Old Party and tea party lawmakers who are upset that House Speaker John Boehner and Senate Republican Leader Mitch McConnell agreed to the plan to reopen government without extracting any limits on President Barack Obama's health care law.
Whatever the future of the troubled law, Senate Republican Leader Mitch McConnell vowed he would not permit another government shutdown.
"I think we have now fully acquainted our new members with what a losing strategy that is," McConnell said in an interview with The Hill newspaper.
Tea party Sen. Ted Cruz of Texas told ABC News he wouldn't rule out using the tactic again, when the same budget and debt questions come up next year.
"I will continue to do anything I can to stop the train wreck that is Obamacare," Cruz said.
That divide defined the warring Republican factions ahead of the midterm elections, when 35 seats in the Democratic-controlled Senate and all 435 seats in the Republican-dominated House will be on the ballot. In the nearer term, difficult debates over immigration and farm policy loom, along with another round of budget and debt talks.
The animosity only intensified as lawmakers fled Washington this week for a few days' rest.
The Twitterverse crackled with threats, insults and the names of the 27 GOP senators and 87 GOP House members who voted for the leadership's agreement that reopened the government and raised the nation's borrowing limit. Republicans got none of their demands, keeping only the spending cuts they had won in 2011.
Within hours, TeaParty.net tweeted a link to the 114 lawmakers, tagging each as a Republican in name only who should be turned out of office: "Your 2014 #RINO hunting list!"
"We shouldn't have to put up with fake conservatives like Mitch McConnell," read a fundraising letter Thursday from the Tea Party Victory Fund Inc.
Another group, the Senate Conservatives Fund, announced it was endorsing McConnell's GOP opponent, Louisville, Ky., businessman Matt Bevin.
"Mitch McConnell has the support of the entire Washington establishment and he will do anything to hold on to power," the group, which raised nearly $2 million for tea party candidates in last year's elections, announced. "But if people in Kentucky and all across the country rise up and demand something better, we're confident Matt Bevin can win this race."
The same group pivoted to the Mississippi Senate race, where Republican Thad Cochran is weighing whether to seek a seventh term. Cochran voted for the McConnell-Reid deal, so the Senate Conservatives Fund endorsed a primary opponent, state Sen. Chris McDaniel, a private attorney the group says "will fight to stop Obamacare," ''is not part of the Washington establishment" and "has the courage to stand up to the big spenders in both parties."
There were more tea party targets: Republican Sens. Lindsey Graham in South Carolina and Lamar Alexander in Tennessee also are seeking re-election.
To her Facebook friends, vice presidential candidate Sarah Palin posted: "We're going to shake things up in 2014. Rest well tonight, for soon we must focus on important House and Senate races. Let's start with Kentucky - which happens to be awfully close to South Carolina, Tennessee and Mississippi."
Opponents of the tea party strategy to make "Obamacare" the centerpiece of the budget fight seethed over what they said was an exercise in self destruction. Many clamored for Boehner and McConnell, the nation's highest-ranking Republicans, to impose some discipline, pointing to polls that showed public approval of Congress plummeting to historic lows and that most Americans blamed Republicans for the government shutdown.
