I am not talking about the period after McCain won the Republican nomination. I am talking about the period before then, when many conservative commentators and others in the grassroots were more afraid of Hillary than anyone. At the time, it was conventional wisdom among conservatives that Obama would be easier to beat.
After McCain won, Rush transitioned into the so-called operation chaos.
Personally, I suspect there were enough crossovers from both major parties to result in an election between the two least qualified candidates.
The point of operation chaos was really by setting Obama and Hillary at odds and putting pressure on them both to defeat both and give the Republican a chance. It was also to undermine the messianic image of Obama.
The problem was McCain did not campaign in any meaningful way. McCain's defeat would have been worse with out what Rush was doing and without Sarah Palin.
You claimed that Rush urged his listeners to cross over and vote for Bambi. I don’t recall Rush ever encouraging his listeners to cross over and vote for Bambi, either before Mccain got the nomination or after. Was McCain his choice in the primaries, obviously not, but once he got the nomination he tried his best to help the idiot out. Unfortunately, McCain did his best to lose to Bambi.
