Romney’s biggest problem is that more than half the money he has collected this spring and summer from his most generous donors is controlled by entities whose priorities may no longer align with his by election day. ...Slate
It's about campaign finance -- about who gets to use which part of which huge donation. How much goes to the Republican National Committee? What goes out to state parties needing funds? How much into Romney's campaign fund?
And, increasingly, how much is Romney worth to the party and its donors now, fewer than 50 days from an election he seems poised to lose? How much does a party or a PAC or an individual want to turn over to Romney's flailing campaign when the same money might be more effectively used to reelect a Republican to the House, or beef up the challenge to a Democratic senator? And what if he's now becoming poison to individual Republicans in races for seats in Congress?

The worst scenario for the Romney campaign would come if the national or state parties begin to see his candidacy as a lost cause, or decide to make congressional majorities—or gubernatorial, state row-office or legislative races—a priority instead. In 1996, Bob Dole’s campaign faced such a reckoning starting after his first debate against Bill Clinton failed to move the race in his favor, and party leaders redirected resources to protect Republican interests elsewhere. Romney is yet far from that point, but a cascade of further bad news and pessimistic polls could leave him quickly isolated.
