Probably quite a few, but I am merciless with email; if I don't recognize the sender and the title of the email doesn't resonate with me, I delete it. I know that a lot of it comes from various Republican or "conservative" political causes, even from Republicans I wouldn't vote for unless their opponent had a Nazi tattoo and hated blacks, women, and rural people. I get a bunch of requests in regular mail, too, and that is shredded and ends up in my compost pile.
I don't make political contributions anymore because they not only take your money, but they also hound you endlessly and sell your contact information to others who do the same. The last political donation I made was to Ron Paul in 2012, and now every Republican running for office, or who has a cause, thinks I'm an easy touch.
