The NRSC has announced it would not lift a finger to help her in the general election and Rove was raving after the loss of Castle, his butt-buddy.
I don't doubt that the national committees will withhold funding for her if they think she can't win. If you think she can win, you can always spend some of
your money to help her.
I've no idea what's up with Rove. Everybody has a bad day now and then, and it's certainly understandable that a strategy and numbers kinda guy like Rove would be dismayed by the probable loss of a Senate seat.
Or, you know, it could be some sort of grand conspiracy by "The Establishment" to poke you in the eye.
The NRSC won't even link to her campaign web site or give her a Bio blurb:

Impatient much? The election returns haven't even been finalized yet.
Give 'em time to absorb the results and decide how to proceed. They'll be on board, you'll see.
As for O'Donnell's chances, Angle was in a similar situation after her nomination vis a vis Harry Reid. I'd expect a bump in her numbers merely from name recognition after last night. If she had party backing (NRSC) & funding and the GOP Establishment manages not to throw hissy fits and disparage her, I'd expect her to be within the margin of error before the general election.
Angle is playing in mostly conservative Nevada. Delaware is a different matter altogether.
You need to be prepared to accept the possibility that a far right conservative won't go over well in the heart of liberaldom, and that the reason for her failing there would have nothing at all to do with lackluster Republican funding.
If she improves significantly in the polls over the next week or two, shows that she has reasonable chance at willing, then she'll get support from the national committees. If she doesn't, then nobody is going to waste any effort or money on her campaign.
