Stop making excuses. There is a clear choice this time. An incumbent who promises the World and delivers nothing versus a business man with a proven track record of professional success in job creation, budget-balancing, and ensuring profitability.
It may be a lesser of two evils again, but if you do not vote you are essentially voting to retain the sitting P.O.T.U.S.
I implore you to seek out the candidate you feel will best suit your own and the Nation's interests.
Edit: At poster above. A vote for the third party is also a vote for the incumbent. Stop wasting your vote.
People NEED to get the fuck out of the mindset that a third party vote is a wasted vote. If I'm not mistaken, voter turnout in the US is something like 40-50% each election. If the portion of that 50-60% that just isn't voting because they hate the two main options went out and vote 3rd party...along with people who are voting for "the lesser of two evils" then who knows a 3rd party could do really well, maybe even push for 2nd place or something and make a real splash.
If you just want a short term lesser of two evils, go ahead and vote Romney...but if you wanted potential long term change I'd be voting 3rd party.
