As I recall, Rush did praise Zogby extensively after the '94 election. And, admittedly, Zogby deserved it. I don't know about Rush commissioning a poll from him, but it's certainly possible. The question I would ask is, has Rush (or any other reputable conservative voice) praised Zogby since?
Two more points:
1.) Zogby greatly harmed his 'polling' credibility when he blew the 2002 elections, e.g., election day he indicated that the Florida gubenatorial election was a dead heat, yet Jeb Bush won by 13 points!!!!
2.) Fox News/Opinion Dynamics just released its most recent poll (Sept 9-10, 2003):
Overall Job Approval (registered voters)
9/09-10/03 58% approve 33% disapprove (+25)
8/12-13/03 57% approve 34% disapprove
[Hmmmmmmmmmmmm, doesn't look like the President's ratings have "tanked" to me! Actually, his ratings have remained remarkably stable AND high (at approximately 60%) despite RELENTLESS attacks by the Democrats and their media enablers!]
Job Approval relative to Terrorism
9/09-10/03 65% approve 29% disapprove (+36)
12/03-4/02 66% approve 22% disapprove
