Very, very ignorant people vote. Very, very psychotic people vote. Their reasons range from the bizarre to the irrelevant ("some of the people who believe in small-government discriminated against me or my ancestors") to the superficially logical, the latter including the Kantian-style dictum that the free market is based on "selfishness" and "all forms of selfishness are evil."
Then they haven't read Ayn Rand's, The Virtue of Selfishness yet. . and probably never will. Do they read at all? Do we need a PreTest to Vote? Not to mention Art's old requirements of 1. Tax Paying Citizen - bring your 1040 2. Veteran or currently serving - bring your DD-214 3. Photo ID - bring your Driver's License + I think I'll add number 4. Pass a Pretest on the Candidates and Issues.
Sound Logical? Wish we had a country built on Voters that had to pass these 4 requirements to Vote. Maybe after Revolution II. . .
