People like you and me.
Again, I implore you all to visit
http://www.opensecrets.org/overview/DonorDemographics.asp?cycle=2002 and see of all those willing to drop 100K+ which party they gave to.
These are individual donors.
Heck, go see where big money goes as well:
http://www.opensecrets.org/overview/topcontribs.asp?cycle=2002Seems the top nine here are pretty solidly DNC
To be fair, this next group seems to be tilted a bit more to the GOP with more leaning or strongly GOP, but the GOP doesn't have a single "solidly GOP" (90% of contributions or better seem to categorize a group as solidly one party or another)
http://www.opensecrets.org/overview/industries.asp?cycle=2002I've not done all the math, but I'm pretty sure the GOP gets it's fundraising advantage from the individual donors and not large corporate or wealthy patrons.
