Dick Cheney isn't the only former Bushie to jump on a soapbox: Former Homeland Security Secretary Tom Ridge called popular radio host Rush Limbaugh "shrill" and offensive in an interview Sunday on CNN. "Let's lead our party based on some principles that have been very much a part of who we are for decades," Ridge said of Limbaugh. "And let's be less shrill in terms of—and particularly, let's not attack other individuals. Let's attack their ideas." His remarks come after a dust-up between Colin Powell and Limbaugh. Powell said Limbaugh was leading the party in the wrong direction and the radio host shot back, telling Powell to become a Democrat. Ridge suggested Limbaugh should direct his 20 million followers to problems in the Democratic Party instead of encouraging Republican infighting.
