Can I have my money back?

So one thing I hate about election time is the damn phone calls. I loathe being called by a recording to explain why I should or should not vote for candidate x, y, or z. I especially loathe it when the voicemail (it's always voicemail, I rarely pick up my home phone) is just a recording of how bad the other candidate is. It goes to my whole hatred of attack ads. I could not care less what candidate x is or is not doing. Tell me what YOU are doing. I think after this election I'm not going to vote for any candidate whose campaign includes phone calls. I'm going to make a list of which candidates call and leave me voicemails and I'm not going to vote for them. They may be the only candidate who is pro-choice, pro-gay marriage, pro-puppies and kitties on the ballot but I will not vote for them because they've pissed me off. (obviously it is too late for this election because I didn't keep track of the 4 different candidates who called the past two weeks. FOUR candidates for a freakin' primary election - although since I didn't keep track it could actually be the same candidate who I got called about 4 times... either way, there were 4 voicemails at home).

I was thinking about this whole stance yesterday before hopping in the shower and it made me wonder... if I had donated money to a candidate who then called with one of those recorded messages could I ask for my money back? Can you ask for your money back once you've donated it to someone? I think I should be able to. "You've pissed me off, I'm no longer supporting you... give me my $20 back!" I like that idea. :)
