Uh, chicken and egg problem. Simon isn't raising big money for a couple reasons. First, he has his own money and donors traditionally feel a rich guy should pony up a substantial amount of his own cash before they help. You can argue about whether that is fair or not (I have mixed feelings) but the perception is that Simon can self-fund, and if he doesn't want it bad enough or have enough confidence in his own campaign to spend his own nickle first, why should they give?
Second, major donors want to give to a party/campaign that has their act together. Maybe Steel should have kept his mouth shut, but Parsky has done nothing but annoy conservatives since he came on the scene. There has always (at least when I lived in Cali) been a disconnect between big money RINO donors who give to keep their taxes low and volunteers who care about other conservative issues (abortion, guns, etc.) But some people (example: Tom Fuentes in Orange County) know how to work with both groups and get them to work with each other. As long as Parsky keeps stirring the waters and leaking this stuff, donors close their wallets.
So Simon doesn't spend his own money, since he had no commercials he doesn't do as well in the polls as he could be doing, donors hold off giving, Simon has no money for ads, he keeps dropping in the polls, chicken egg chicken egg. However, Simon has just purchased ads and come up with some great endorsements so to me it looks like he's on the offensive. A ten point difference four months out is absolutely winnable.
The Bush people have confused the ability to raise money with political smarts. Parsky may be a great fundraiser, but a smart pol would have figured out a way to work with conservatives.
That's an impossibiity, if "conservatives" as self-defined here on Free Repbublic are any example.
