Trying to further reach out to conservative voters, Rudy Giuliani has begun airing radio ads on the Rush Limbaugh and Sean Hannity programs. The ad goes: "Hi, this is Rudy Giuliani… My campaign is about leadership and optimism. We need strong leadership to stay on offense in the War against Terrorists. We need supply side policies and reduced government spending - fiscal discipline - to keep the economy growing. I need your support in this campaign. Please go to JoinRudy2008.com to sign up or volunteer."
