I've heard that same strategy time and time again for years, and I think it's foolish. I have no desire to live under a scorched earth just to point fingers at Democrats and say, "See? We told you this would happen."
So I will vote for whomever the Republican candidate is: Romney, Gingrich, Santorum, ...
I have the "luxury" of living in a solidly blue state. I am voting for the Green Party candidate, and I urge all Republicans and fellow conservatives in similar states to do likewise.
I see no downside to breathing life into the Green Party. Thanks to lax immigration enforcement and voter fraud the Democrats are eking out a voting majority over the Republicans. Splintering off some of that vote to an invigorated Green Party is a good short-term strategy for keeping a Republican edge in Congress and the Whitehouse.
Everybody at FR being harangued into voting for the lesser of two evils (i.e. McCain) or deluding themselves into believing they were voting for Palin didn't do us much good last time, did it?
I can just see what happens if Romney is the Republican candidate and he picks Ryan or Cantor as his running mate and the desperate eyes of the dispirited conservatives light up in unison to proclaim:
We're not voting for Romney, we're voting for {insert true conservative name here}!
