I’m not a fan of Bradblog but he’s not impressed by the Dems Koch campaign either
Koch Is It! Dems’ 2014 Campaign Plan Revealed!

So, running against The Koch Brothers brings in three times as much money as running on…whatever else the Dems have been trying to run on so far this year.

It’d be nice if the Democrats gave voters something concrete to vote for. It might even solve their oft-cited problem of D voters not turning out for mid-terms. Why should they, after all? That’s not a criticism, that’s an actual question.

You also might want to ask them why they aren’t doing much more to fight against the madness unleashed by the infamous Citizens United in 2010 and the way that Republicans (particularly the Kochs and Karl Rove) have gamed every last inch of whatever scraps are left of campaign finance law in this country. Come to think of it, a hard promise to pass laws to effectively overturn Citizens United and restore campaign finance enforcement at the FEC would be just one concrete policy that Americans might actually turn out to vote affirmatively for. And, Democrats could beat up on the Kochs all they like in the bargain. Win-win! So, of course, Democrats probably won’t do it.
