Reply #3: That's a good idea, but I'm imagining the telemarketer dealing with that info ...

[gauguin57]

... a telemarketer who was probably some apolitical, unemployed person who is happy to have a job and to make calls all day long for anyone (who cares who), and who doesn't want to rock the boat by telling his/her boss that someone said they're going to donate to the DNC.

I try to remember that the person on the other end of the phone probably doesn't give a crap about what they're saying into the phone -- they're just happy to have a paycheck so they can feed their kids.

So, I just say, "Thanks, but I'm not intersted. Good-bye." and hang up.
