Not really that type of an issue, it is managing information. You leak information you want others to see. Coakley showed her internals because she wants democrats from CT and NH to flood into the state to save her ass. My guess judging by what I've been reading and hearing, she didn't really plan that great of a GOTV effort. I expect to be reading about what a disorganized cluster it was on Wednesday morning.
Brown was an underdog so he probably has one of the GOP's top GOTV directors already in place and a plan has been formulated and is being implemented for 3-4 weeks.
The mechanics of a campaign are not partisan. I'm pretty sure the GOP operates the exact way the DNC does in that regards.
ATJ, up here, the Dems aren't getting involved in the Senate race. They are, however, taking a very close look at it and reacting accordingly. Carol Shea-Porter (aka, Che-Porter) was quite content in her formerly "safe" House seat, but rumblings have it that she may be reconsidering a run for Senate this year, given that she'll likely lose in November, and could potentially defeat Hodes in a Dem primary, given her more favorable rating among Dems in NH. Ayotte leads Hodes by nearly 10 points (remember, Obama won NH by 9, and Shaheen beat Sununu by 7). Hodes leads other named GOP challengers, but only because of name recognition, not actual policy.
They're looking here in NH, they're getting information not released to their base, and they don't like what they're seeing.
