You can think of it this way: Essentially the Democrat Party has split and one half has merged with the Republican Party. So by voting ‘lesser of two evils’, you’re voting for the same people you used to be voting against - completely unprincipled...stupidity.
Ah yes...that's why George W. Bush (hardly Reagan, is he?) would be welcomed with open arms if he switched parties and asked to give the keynote speech in Denver.
The idea that there's no difference between to two parties is for children. Get a grip.
