So Rush has challenged Obama to a debate. Interesting. Of course, the likelihood of Obama accepting approaches zero (something everyone, including Rush, knew already), but it's an amusing thought nonetheless. It is also patently ridiculous.
Let's turn this around so political biases won't impede the perception of just how silly this is. Let's take someone on the left, who's deeply partisan, not averse to bending facts to fit his views, with a big mouth, millions of fans, and just for shits and grins, has a weight problem: Michael Moore. Now imagine Michael Moore challenging President George Bush to a debate. Should Bush have accepted? Of course not! He's the President of the United States for crying out loud! Time is not something he has in abundance, and the precedent would be unwieldy to say the least. Are we going to expect every president to accept every debate challenge from famous people, even ones he may mention in political discourse? The idea is ridiculous. Whether the person challenging the president has views with merit or not is completely beside the point.
I think this guy nailed it as to Rush's motives, and the reasons the challenge falls flat. He had his chance to do this for a long time (an interminably long time) during the election. Obama met with Rick Warren after all, he might have met Rush as well: as candidate Obama. But President Obama has better things to do.
What I find amusing is remembering how Rush acted when the Republicans took over congress in 1994 with Bill Clinton as president. Rush went through Clinton's speech at the time, line by line, responding to Clinton's remarks about working with the new GOP congress. Rush kept reminding Clinton, literally jumping up and down with glee (this was on his TV show, which I used to watch, ahem, religiously) that he had just been voted out of relevancy, and the congress didn't need to work with him. The voters had spoken, and they wanted Republicans.
I think that was a good argument then, and it's a good argument now. You had your chance to debate on the battlefield of politics Rush: that's during the elections. You either didn't think of it, or decided against it, but for whatever reason, that's that. Obama is president now, the voters soundly rejected your political position. While you can and should continue to argue that position, you have no business expecting the winner of the game to prove he can score a goal against you.
Finally, what is with this trend with modern conservatives and always wanting to fight their fights on the wrong battlefield? Rush's challenge is not unlike the challenges to debates creationists are always levying at scientists. They avoid the scientific battlefield of the peer-reviewed literature, writing popular books instead. They complain about court decisions that go against them, but don't appeal. They also whine (just as McCain's supporters have) that the reason they lost was because the game was rigged against them. All suggest minds not at all open to the idea that they might be wrong. Thus we get the "I want Obama to fail because I want America to succeed" argument, as if that is the only possible outcome. Such is a dangerous mindset in challenging, changing times. Closed-mindedness is not something we can afford.
