This is not Heaven, choose the best. Too bad, it's reality.
I used to buy into this cliche of "if I vote between two evils, I will still end up with evil" Yup, but there's no other way, unless you want to drop out of the process and not have a say.
I say a Democrat is always more evil than the Republican.
Likely true, but it's not the only thing to consider.
If Romney wins, Boehner will support him in putting most of Obamacare into effect.
If Obama wins, Boehner might fight against Obamacare.
Those are are options if the GOP is dumb (or corrupt) enough to install Romney as their candidate.
Never say always, sometimes they are equally evil, and sometimes the Dem is more honestly evil and the Repub is stealthily evil. It becomes a Hobsen’s choice.
A childish principle, taken to extremes. There will never be a totally good candidate so voting for some "evil" is inevitable. The appropriate guide is to vote for the best candidate available.
