There are a number of characteristics that make up the establishment that has led to a tea party revolt within the party. The establishment tends to support ideologically moderate candidates whom they deem “safe” and attempt to push their chosen candidates through primaries. They view winning at any cost more importantly than winning with a conservative candidate. Such a position has led to establishment support of politicians such as Arlen Specter, who left the party to join the Democrats and cast the deciding vote for Obamacare, and Charlie Crist, a former popular Florida Republican who bailed the party because he was certain to lose the GOP nomination for Senate in 2010.
The establishment also tends to operate under a “good old boy system,” to paraphrase Sarah Palin. They follow the next-in-line strategy when it comes to elections, deciding who “deserves it” based on how long they have been around Washington and who has best built up a network of fellow establishment insiders. This has led to a number of unimpressive presidential candidates such as George H.W. Bush, Bob Dole, and John McCain. The establishment also props up candidates in senate, congressional, and gubernatorial elections and regularly had their way until the post-George W. Bush tea party revolution.
The chief antagonists of the Republican establishment are 2008 VP candidate Sarah Palin and South Carolina Senator Jim DeMint. Also, a number of organizations have been created to oppose establishment candidates and support conservative and tea party alternatives. Those organizations include Freedom Works, the Club for Growth, the Tea Party Express, and hundreds of local grassroots organizations that have sprouted up since 2009.
Sarah Palin has been the most effective anti-establishment activist and has turned multiple primary elections upside down. In both 2010 and 2012, her endorsements helped catapult a number of candidates pull of come-from-behind wins against presumptive nominee in a number of races.
