Obama's raising a lot of it.
I know some people find the "who's raising the most money" thing one of the more annoying things about political coverage, but I actually think it's pretty important. Getting the support of lots of donors greatly diminishes the importance of big donors and big donor networks.
Clinton, too, has raised a decent amount of money from smaller money donors, so this isn't just an Obama thing. The important thing is that as more campaigns understand that there are ways they can try to attract large numbers of small donors, they'll reorient their priorities. Those $2000/person checks aren't going away, of course, but their relative importance might decline.
