Then, after mentioning that Kerry has said he's going to increase capital gains, I ask if they have money in the stock market, such as retirement money. When they say yes (as most do), they are shocked to realize Kerry's going to take some of their money there also.
Hence, they realize that voting for Kerry is directly against their financial interests.
I've lost count of the number of mis-led people I've quickly flipped with this simple argument.
LOL. I'm really poor at the moment (I've had some really bad life reverses, disabled, etc). When I run into a Kerry supporter, I love to yank their chain by saying, "Oh, he's such a liar, totally unfit to be president - but I hope he wins! He's going to tax everyone and give me all their money! And I'll get free health care, and I won't pay for it!"
This can go on for a long time. Sometimes they agree, but after a while they start to get really uncomfortable when they realize I'm talking about THEIR money. It can get really funny. Of course, people who know me well realize fast I'm not quite so shallow, but a total stranger you can keep going for quite a while.
