Obama is the wrong candidate to indicate dissatisfaction with Romney...there are at least 3 parties.
The election, as most are, appears to be a question about enthusiasm. Simply failing to vote for Romney is at least half as good as voting for Obama in terms of not supporting the GOP's directorialist candidate. However, a vote for Obama does not indicate to the GOP what it needs to know. Furthermore, and very importantly, for anyone not living in Ohio...your vote is not a marginal vote. If you live on the left coast, or the Northeast, your state is voting for Obama. If you live in the south...your state is voting for Romney.
I recommend a vote for Gary Johnson. Balanced budgets, No foreign wars, veto a lot.
- It has half the electoral impact of voting for Obama...which doesn't matter in most states.
- It tells both major parties what's wrong with them.
- Gary Johnson is the strongest libertarian candidate we've seen probably ever...and is currently polling to pick up 10-15% of the 3-way vote in New Mexico.
- A few percent for Johnson in some other states...especailly if it's the margin by which Romney loses...would send a very strong signal to the GOP...much stronger than the signal an Obama vote would.
