If that's the case than it certainly is a low-blow (I wouldn't be too surprised - I know he can't raise his arms above his head), though it still seems slightly lame to me (I mean - they do have programs that take voice instead of keyboard). I'd have to do a fact check.

And you're right about pissing off a demographic. However, having seen the ad, I don't remember it specifically attacking McCain because of his age.

In good news: Obama apparently does have something to attack McCain with. Karl Rove said McCain's attacks were too "dishonest."
