Stupid self-mutilation will not be salved too much by trying to show hypocrisy by supporting another resolution against Rush. This is not your job. In the long run, anti-war sorts (or those behind any sort of controversial speech) liable to be tarred by this sort of thing are more likely to be libs anyway.
BTW, Glen Greenwald has some good stuff this week, with special focus on two key HC supporters. You know, the next Dem candidate for President. No need to vote in your caucus/primary. She voted for the let's help the push for war with Iran resolution too. Doesn't want war, surely, just enables it.
