This is real simple. Anyone who doesn't vote GOP wants the Democrats to win.
Some do it because they are really Rats and make no pretense about it.
Some do it because they really are Democrat/leftist/protectionist/socialist wolves in Republican sheep's clothing. They pretend to others (and themselves) that only they are the "real" Republicans or "real" conservatives. See, e.g., Buchanan paleoconservative types. In fact, they are as phony as a three dollar bill.
Others do it out of often malicious spite, or pompous self-righteousness (which are often the same thing). See, e.g. single issue voters (you know who you are).
And some are masochists (a form of neurosis). These are the types who would rather serve under Nancy Pelosi than rule with George W. Bush, even when politically they are much closer to Bush.
The Rats require all types, and count on them to attempt to win elections. This is why Rats are not healthy either in your house or in your Congress and/or White House.
Note to self: principles are actually pompous self righteousness. So when I "hold my nose" and vote for the RINO Mark Kennedy this year, I won't actually be sacrificing principle, I will be shunning selfish self righteousness!
I have seen the light!

Wrong!
And I don't fit in any of your reasons listed.
And another (wrong) amateur pop psychologist is heard from.
