Again, the leverage that works now is not giving the Dems any money 'til they clever up (as opposed to the idea that your only leverage is your vote).
That would include down-ticket races, unfortunately. Why?
Because, as any economist would tell you, money is fungible. If you give $1.00 to Good Guy Dem A, all that means is that the DNC doesn't have a spend a dollar on Evil Fuckhead B. Eh?
This happy thought is prompted by the Senate having voted for cloture on FISA, meaning a filibuster is "pre-dead."
That makes FISA a done deal, so it's all over but the shouting and the posturing, which can take place at any propitious time. I'm betting after the Convention, so as not to subject Herr Professor of Constitutional Law Barack Obama to any pesky questions.
The Dems just sold the Constitution for a few pieces of silver from the telcos and a little more margin for a couple of Blue Dogs who'll fuck us over, soon as look at us. Tell me why the party deserves any money at all?
