This is instructive. The D-Trip is not afraid to play in primaries:
As the cycle wages on and Republicans appear more vulnerable this November, those extraordinary circumstances have become the norm.
The addition of Iraq veteran Jon Powers to the DCCC’s Red to Blue program last week made the New York House candidate the latest to gain the national party’s fundraising assistance.
Over the previous month, the committee used Red to Blue to back another New York candidate, as well as candidates in open primaries in Alaska, Arizona and Louisiana. It had previously added a candidate in Michigan in March.
Only six races with competitive Democratic primaries are currently listed as “toss-up” or “lean Democratic” by the Cook Political Report. The DCCC has now picked a side in all six of them.
One of the raps against the NRCC in the spring special slaughter is that they refused to support the more electable (or less unelectable) candidates in LA-6 and MS-1. Nobody likes to take a heavy handed approach when you have two or more competitive candidates running. As a former party committee operative, I can tell you that the decision to weigh in for a candidate, or not to weigh in at all, heavily shapes perceptions of the national GOP among grassroots activists, rarely for the better.
But people don't like to get beat either, especially when the defeat was preventable. And you've got to weigh that.
Over the long term, there's nothing that says that this targeting function in primaries can't happen outside the party committees, through outside groups that earmark small donations for candidates.
Sites like this one and RedState can serve the NRCC function in races where the incumbent or establishment candidate needs to lose in order for us to win the seat. The NRCC won't tell Don Young to take a hike, even though we lose the seat with Young and keep it with Sean Parnell. They'll need the millions left in his bank account (after he's done with the legal bills). But we can. And the NRSC won't tell Ted Stevens, the most senior GOP senator, to step down for the good of the party.
There are times when the NRCC/NRSC's targeting sense won't align with ours, or where they won't play where we will. And that's fine, so long as someone is policing against nominating deadbeat candidates for the fall.
