My summary of this non-issue:
Ons should not hope that Obama or any president simply fails, because there should be some area of commonality for the 'good of the nation'.
To say otherwise is to say that either the speaker or Obama wants nothing but the destruction of the nation, which hardly seems appropriate or correct.
On the other hand, there are areas pretty much everyone has in which they disagree with Obama. It's perfectly ok to hope he fails in specific policies you think are wrong. Rush Limbaugh needs to keep his audience that is based on hating liberals, and so he's going to use straw men and hyperbole in dishonest commentary to flame the fire.
I'll even condone ambivalence about a president's success insofar as it helps him get bad policies implementsd. If Bush were to do great at one thing that gave him the popularity to get something else (say, destroying Social Security) that was a much larger harm, I can see not wanting him to get that credit, to remain politically weak. But it's better to want him to get the good done and oppose the specific bad policies, if possible.
Rush is not that interested in talking about the areas of agreement usually - why would anyone want to hear Rush on those areas?
Anyone who thinks Rush is above hypocrisy in demanding loyal support for a Republican president and undermining a Democratic president, is pretty blind IMO. This is a guy in a group who were more than happy to imply the democratic president is a murderer, to cripple his ability to function legitimately, to abuse the impeachment process.
It's fine to condemn Rush for his wrongful commentary, but better to suggest not listening to his waste of a program IMO.
Instead, how about an actually excellent commentator, like:
Gleen Greenwald
or the best collection of commentators on the web IMO:
