And let's not forget all of the Ron Paulers (both independent and liberal conservatives") who projected all of their extreme idealism and wild fantasies onto a single candidate. When I say "extreme idealism", I don't mean that the ideals are bad - just unaccomplish-able for a single president in one term (or even in two).
But take the extremist Marxist (Obama) who thought he'd fundamentally change the government when he became president. He couldn't do it one term - nor will he get it in two (hopefully). People forget that the Constitution, which they're so eager to tell others to read, purposefully divides the power in government among the Executive branch, Congress, and the Courts.
These people quit trying when Ron Paul failed.
