And I'd point out that the criticism of Obama in this ad is criticism of AN ACTUAL LEGISLATIVE ACTION, of a vote Obama actually made, of a real honest to goodness ISSUE.
But it's not. It's an ad that implies that Obama wants to force kindergartners to be taught all about sexual matters. Which is a distortion, no matter how you look at it, and a distortion aimed at disturbing people. It's not at all about disagreeing with the legislation.
And your defense of the ad is sad indeed. By parsing the language carefully, you can show how
technically it's not a lie. That's exactly what political admen do, so they can justify ads that avoid real issues and instead present the other candidate in the worst possible light. The fact that it's a distortion doesn't seem to bother you.
You can find poorly crafted legislation all over the place. Sometimes it's from lack of thought; often it's the result of compromise. And when a candidate votes for it, thinking it's better than nothing, or the best compromise that can get passed, you can then pick it apart and "prove" that candidate x is in favor of, or opposed to, just about anything.
This is precisely the type of ad that lowers the entire electoral process.
