Limbaugh - there was a story that an organization that Specter benefits from obtained a $50,000 donation from Soros, and Specter called Limbaugh to rebut the charge. Limbuagh goes on the say that Limbaugh asked Specter about the 9/11 committee. "It's up to listeners to judge whether the cahrge was true." Limbaugh is saying that the charge that Specter got a donation directly from Soros is false.
Caller is reminding Limbaugh that Toomey is conservative. Limbaugh is saying it's good news that Toomey is gaining ground, and that the GOP is nervous about Specter. ALso that Bush and Santorum support makes people wonder about GOP core principles - that support for incumbents only is cause for concern.
Limbaugh is saying he is glad the person called and brought it up. Moving on to Iraq stories.
