It’s not that the squiggly lines aren’t fun to watch. Rather, they’re too much fun to watch. It’s hard to avert your eyes from them. It’s hard to separate your own, independent reaction from theirs. And it’s certainly hard to integrate back into to the non-squiggly universe once you’ve gotten hooked on the squigglys.

[Also – the CNN focus group doing the dialing was clearly not “undecided” but was in the tank for McCain from the get go.]
