Jason made a grammatical point. As an editor at NR, he has probably corrected my improper us of who/whom more times than I know. But I’d like to nitpick at Joe Biden anyway, because this one is a pet peeve of mine. Biden said this:

The issue is, how different is John McCain’s policy going to be than George Bush’s? I haven’t heard anything yet. I haven’t heard how his policy is going to be different on Iran than George Bush’s. I haven’t heard how his policy is going to be different with Israel than George Bush’s. I haven’t heard how his policy in Afghanistan is going to be different than George Bush’s. I haven’t heard how his policy in Pakistan is going to be different than George Bush’s.

It’s not different than, it’s different from.
