The Republican Party is in search of a message to attract voters who are angry with just about everything -- healthcare, the U.S. deficit, Wall Street bonuses, increased unemployment and home foreclosures to mention a few.

"There's a lot of anger out there and there's a lot of frustration," said Republican Senator John McCain, who was defeated by Democrat Barack Obama for president last year.

Thousands of people are turning up at townhall meetings and "tea party" protests against government policies, he noted.

"So there's something going on out there. And I'd love to sit here and tell you that we Republicans are attracting all of those unhappy people but we're not, we're not," McCain said at a Reuters Washington Summit.

"They're out there kind of in the middle and they haven't found a home. And in fact they haven't even channeled their anger yet," he said.
