No, but fortunately enough Conservatives will boycott a RINO Republican nominee that your vote, and those of your fellows will make no difference.

The enemy within is far worse than the enemy beyond the gate, as the immigration flap should prove on it's face. Or the stripping of eminent domain, or the selling of our ports to foreign governments, or the limiting of our sovereignty as in the LOST at sea treaty... etcetera, etcetera, etcetera. Al these and more pushed upon us by Republicans
The only enemy we face that seriously threatens us is our own Left.
However ... it's still an open issue, in my view, whether 'tis better, in a general election between a hardcore Marxist and a derranged Marxist, to vote the later, or to vote neither. I'll vote the derranged Marxist, and hope we can muddle through. We've survived (more or less) 4 years of Carter and 8 years of B.J.Clinton in recent years; the good men who constituted our federal government did a remarkably fine job.
Really, I figure we have a better shot at continuing this grand experiment in freedom if we keep the Presidency out of the hands of someone [Hillary] who is actually, personally, with the focus of a lifetime, dedicated to destroying our freedom.
Our odds are better if the Presidency in the hands of a raging nut case who [McCain] has not been a consistent Marxist his entire life.
In any case, let's do what we can now to see that we have a better choice this November.
