grenade on this fight but they told us, quote, that could change. the group spokesman telling us, quote, there's been an increased level of donor activity since president obama's budget speech two weeks ago. donor interest has peaked. when asked what sort of resources could be brought to bear on their side of this fight, mr. rove's group reminded us of the $750,000 ad by the group placed last month going after union rights. who pays for that sort of thing when crossroads and crossroads gps does stuff? at one point last year, 91% of the funding for american crossroads came from just a few people. just a handful of billionaires. crossroads gps, however, does not have to disclose to the public who funds them at all. in addition to all of that big money coming from the right on this issue, there are other conservative groups, like freedom works, like the heritage action for america, part of the heritage foundation, i think. also the american action network who are joining in this big conservative apparently corporate-funded counter-offensive.
