Here's my question. Regardless of who created the robocall, what made them think it would work?
Here's my answer. They played the robocall to a sample of their target audience, and upon questioning, found that it made that sample question Mark Udall's morals. Presumably, it also made some of them question the morals of the people who created the message. But on balance, the net effect was to harm Mark Udall's reputation, and that's a victory.
Here's my next question: Who are these people that are willing to believe that Mark Udall supports human cloning?
They would have to want to believe it. Only willing participants in the suspension of disbelief will enjoy the show. It's much more exciting than all this "blah, blah, blah," about the economy, and all you have to do to join it is want to believe there's something fundamentally evil to fight out there. One party is telling you the opposition is Godless. The other party is telling you the parties have policy differences. (It's left as an exercise to the reader to figure out which is which.) To a certain degree I'm being unfair to Republicans. Don't lump them all together. A large minority of them really hate what's happening to the party. They're the fiscal conservatives: deregulators and supply-siders; Libertarians who want to win an election (and therefore become Republicans). The problem is that fiscal conservatism isn't enough to win you an election, so they formed a coalition with social conservatives.
Question number three: How does a group of fiscal conservatives attract another big voting bloc to a coalition?
There may have been other alternatives, but this group decided that the social conservatives were their target. My guess is that social conservatives are inherently vulnerable to manipulation. They're ready to take things on faith. By definition, they're already afraid of the other. I disagree with fiscal conservatives, yet recognize that some of their arguments have merit. For social conservatives, I struggle to to overcome my contempt. These are the people who cherry-pick The Bible (especially the Old Testament, but Paul's letters contain some real doozies, too) for quotations that support their own prejudices.
So the fiscal conservatives adopted the social conservative plank and started winning more elections. The thing is, there are more social conservatives in this country than there are fiscal conservatives, numerically speaking. So now the social conservatives are the party majority, and a character like Sarah Palin is a Power. The first time she suggested that a candidate for POTUS was friends with a domestic terrorist, she should have been laughed off stage. That is not policy. The suggestion is ludicrous.
I took the title of this posting from something I heard David Frum say on The Colbert Report. He predicted that as the Republican party strays further and further off-topic, it will lose more and more of its serious members. Many Republicans agree that it's silly to suggest that Barack Obama has anything to do with terrorism. They will be thinking that they don't want to be publicly associated with a party that makes such spurious claims. Eventually, only the base will remain, that "base" now being the social conservatives who turned out in their millions to prevent gay marriage in 2004. The rural, white rump.
Here's my last question: How do the Republicans get the genie back in the bottle?
The problem is: for every highly educated, right-minded Republican candidate, there's going to be three uneducated populist firebrands like Sarah Palin competing in the primaries, because it's easier to be a firebrand than it is to develop policy. And the social conservatives are in the driver's seat now.
