Not sure where your getting your information, here's my experience with the upper end of the bracket; mid to older professional wage earners, doctors, dentist, attorneys, business guys, ect.. Social liberals, fiscal conservatives typically moderates politically. In my opinion, you're giving this group way to much credit in terms of political clout. The 50K club makes more noise than these guys.
1-2 million bucks net worth doesn't make you wealthy or rich. With entry into the 1% club at 350-400K pre-tax, the top of the bracket ain't attending many 100-200K fund raisers, nor are they buying much political influence as individuals. The earned income guy is "teeny tiny" comparatively speaking to the .1% club.
If the goal is to target the "trick" looking for more than a political hand job, look else where. You've got the wrong group. You need to be looking at the fractional bracket below that of the 1%'ers. After all, how many suitors does a "political whore" really want? One fat sugar daddy vs a bunch of little grubby shits?
