Conservative talk radio hosts including Rush Limbaugh, Shawn Hannity and Laura Ingraham are upset by the fact that Senator John McCain appears to be the front-runner in the race for the Republican nomination.  “We are trying to stop the wanton destruction of the party, the wanton dilution of the party,” said Limbaugh. “We are sick and tired of how the people who seem to be triumphing in our party are precisely the people who seem to be selling this party out in terms of its ideology.”  McCain will have trouble winning in November if he fails to secure the support of conservatives.
