This wasn’t the revolution the tea party had in mind.

Four years ago, the movement and its potent mix of anger and populism persuaded thousands of costumed and sign-waving conservatives to protest the ballooning deficit and President Obama’s health care law. It swept a crop of no-compromise lawmakers into Congress and governor’s offices and transformed political up-and-comers, including Florida Sen. Marco Rubio, into household names.

But as many tea party stars seek re-election next year and Rubio considers a 2016 presidential run, conservative activists are finding themselves at a crossroads. Many of their standard-bearers have embraced more moderate positions on bedrock issues such as immigration and health care, broadening their appeal in swing states but dampening grass-roots passion.

“They keep sticking their finger in the eyes of the guys who got them elected,” said Ralph King, a co-founder of the Cleveland Tea Party Patriots. “A lot of people are feeling betrayed.”

The tea party is a loosely knit web of activists, and some are hoping to rekindle the fire with 2014 primary challenges to wayward Republicans. But many more say they plan to sit out high-profile races in some important swing states next year, a move that GOP leaders fear could imperil the re-election prospects of former tea party luminaries, including the governors of Florida and Ohio.

Fla. Gov. Rick Scott, a former health care company executive who won office by attacking the health law and calling for deep cuts to state spending, later endorsed the health law and signed one of the largest budgets in state history. Similarly, Gov. John Kasich, R-Ohio, and Rick Snyder, R-Mich., are battling their GOP-dominated legislatures to expand Medicaid, a big part of the health law.

Tea party supporters were most struck by Rubio, the son of Cuban immigrants.

As a Senate candidate in 2010, he denounced as “amnesty” any plan that would offer a path to citizenship for those who were in the country illegally. Yet in recent months, he has emerged as a leader of a bipartisan Senate group that developed a plan that includes such a provision. The plan has been panned by conservatives but ultimately could bolster Rubio’s standing with Hispanics, a growing demographic group that has voted overwhelmingly Democratic in recent years.

One sweltering July day, a half-dozen tea party protesters gathered under a tree in front of Rubio’s Miami office, seeking shade as they denounced his support for an immigration overhaul. But the protest soon turned into more of a support group, with the four men and two women grousing to each other about how Rubio had turned into a “back-stabber,” a “liar” and a “flip-flopper.”

The movement’s top strategists acknowledge the tea party is quieter today, by design. It has matured, they said, from a protest movement to a political movement. Large-scale rallies have given way to strategic letter-writing and phone-banking campaigns to push or oppose legislative agendas in Washington and state capitals.

Local activists say they have focused largely on their own communities since Obama’s re-election and the ideological drift of some tea party-backed politicians. Many are running for school boards, county commissions and city councils, focusing on issues such as unfunded pension liabilities and sewer system repairs.

“The positions that people are filling at the local levels are more important for the future of the movement and the future of the country,” said Jenny Beth Martin, co-founder of the Tea Party Patriots, a national umbrella organization. “It’s creating a farm team for the future.”
