The option of third Party/Independent candidates can only divide our Repub vote and insure an Obama win. Now is the time to not only get behind the right candidates; but the right Party; IMHO.
If your candidates/Representatives are not 'Right'; then find a decent Repub who is and support them. If they are right most of the time; and committed to honoring Founding Father principles per our Constitution; get behind them.
Stop thinking in terms of party/lesser of two evils, and start thinking how, in the long term best interests of the country, the GOP must be gotten rid of. The GOP is the biggest impediment to conservatism. In its place will come a real conservative party, a dramatic shrinking of government, huge tax reductions, and restoration of the Constitution.
