Sen. John McCain is starting to sound like a Tea Party “wacko bird.”

In a new fundraising letter for the Republican National Committee released Friday, McCain lashed out at “Barack Obama, Harry Reid and Washington liberals,” who he claimed are destroying the United States.

Liberals, he warned, “have taken us down a dark and dangerous path defined by record levels of debt, ever-expanding government, and a lead-from-behind defense strategy. There’s not much time left to turn things around.”

McCain’s name carries a lot of weight in fundraising because he was the 2008 GOP nominee and is a leading voice of establishment Republicans. But he also toughened his tone to sound more conservative and closer to Tea Party senators like Ted Cruz of Texas and Rand Paul of Kentucky, whom McCain recently labeled “wacko birds.”

Forcefully joining the GOP effort to stall Obama and the Democrats in their bid to take control of Congress in the 2014 elections, McCain said, “There’s too much at stake. The liberals are fully stocking their campaign war chests so they can continue to rubberstamp every big-government, job-killing, tax-and-spend scheme Obama dreams up. We must not let the liberals win — so we need you to stand shoulder-to-shoulder with our Republican team.”
