WASHINGTON — The Republican establishment’s much-anticipated pushback against the Tea Party wing is underway. House Speaker John Boehner made that clear Thursday, when he renewed his denunciation of groups that try to defeat GOP incumbents they consider too willing to compromise with Democrats.
Some Republican loyalists wonder what took so long. The US Chamber of Commerce recently took steps to help mainstream Republicans in party primaries, but Boehner’s high-profile outburst will move the effort to the GOP’s front burners.
Cheering him on are mainstream Republicans who angrily watched for three years as hard-right groups exercised remarkable clout in the party, Congress, and elections. Tea Party-backed nominees helped Republicans win control of the House in 2010, but they also lost several Senate races viewed as winnable, keeping the Senate in Democrats’ hands.
This past summer, uncompromising House Republicans forced a partial government shutdown that damaged the party’s image, just as Boehner warned it would.
Many Republicans also feel conservative activists pushed presidential nominee Mitt Romney so far to the right on immigration and other issues that it eased President Obama’s path to reelection last year.
‘‘The establishment has no choice at this point,’’ said former Representative Tom Davis, a Virginia Republican who criticized the Tea Party’s influence. ‘‘So they’re taking them on.’’
‘‘To follow these groups is a downward spiral,’’ Davis said.
Those groups will fight back hard, Davis warned, and it’s not clear which faction will prevail in next year’s midterm elections and beyond.‘‘They’re dug in pretty hard,’’ he said.
For a second straight day, Boehner criticized groups such as Heritage Action, the Club for Growth, and Americans for Prosperity.
These Washington-based organizations vary on priorities and tactics. But all have sharply rebuked Republican leaders on key issues. And they have aided insurgent Republican challengers who vow never to compromise with Democrats, even if it means shutting down the government or defaulting on the US debt.
Critics say the groups chiefly want to raise cash by constantly inflaming political activists.
‘‘They’re misleading their followers,’’ Boehner told reporters at the Capitol. ‘‘I just think that they’ve lost all credibility.’’
The issue at hand was a bipartisan budget plan that makes modest changes in spending levels. It is meant to avert another government shutdown and budget crisis in the near future.
But Boehner’s remarks appeared aimed more broadly at Tea Partiers who say true conservatives never compromise, and at groups that try to oust established Republicans seeking reelection.
House actions under his speakership, Boehner said, ‘‘have not violated any conservative principle, not once.’’
He then dismissed the activist groups, saying, ‘‘I don’t care what they do.’’
Some Republicans fear an all-out struggle between the establishment and the Tea Party wings, saying both factions’ money and energy are crucial to winning elections. But others say Tea Party excesses leave little choice.
