it is padded by fluff in that "the party" votes to name post offices and congratulate the NY Giants and McCaskill votes with them.

And it also assumes the party is always right. Sometimes the party decides to support a bi-partisan piece of crap - like the Bush tax cut extension, or the Iraq War Resolution (although a majority of the House Democrats voted against that, a majority in the Senate voted for it.

So by that measure, McCaskill would get credit for voting (with Republicans and a slight majority of Democrats) for the Bush tax cut extension and Wisconsin's Tammy Baldwin would get dinged for voting against it. Which, in my mind, is giving McCaskill credit for being on the wrong side.
