Unless it's written really well I hate putting contemporary politics into comics (and it's rarely written well). And yes, while I'm glad the Bush admin. is gone (though I never hated the man himself and thought the comparisons to Hitler et al. from so-called progressives demeaned their own cause) the idea that attacking his policies while he is safely out of office is daring or brave or anything else is ridiculous.
It's like when we have the occasional rant against organized religion in comics - whether it's as ridiculous as Chuck Austen not knowing Catholics don't believe in the Rapture in the Make-Nightcrawler-Pope storyline or OOC as the Superman 2-parter a few years back saying he stopped attending church altogether with his parents in his early teens just because he could hear the hypocrisies of his fellow church members (despite the fact that plenty of other comics before and since have shown him attending the Smallville church with Ma and Pa with no problem, as well as being married in a church). Most comic readers aren't particularly (or at all) religious, so there's nothing brilliant about writers with a chip on their shoulder on the subject playing to their audience.
The same thing is happening with Marvel/DC post-Bush. Now they have a president they like they attack the president they didn't - but only when he's gone and discredited, not when he had 70% approval rating post-9/11. To do it then would have been daring and edgy. Stuff like this? Nah.
