The logic is simple, McCain is a Dem just like Hillary/Obama. If the DNC wins then the Republicans in congress will fight but if McCain wins they’ll go along with every hair brained idea he comes up with. I believe Ann Coulter shares the same position and I suspect she has significantly more insider knowledge than I do.
I personally would like to have a third party option at this point (I would vote for Paul over McCain). This “your throwing away you vote” crap won’t work with two Democrats up for POTUS. McCain will push for amnesty and global warming legislation and likely get what he wants. Hillary/Obama would likely get shutdown in the legislature.
Grid lock is our best hope at this point.
To paraphrase, it all depends on what your meaning of "gridlock" is...
Is it gridlock with a Democrat president, a democrat-controlled house & a Democrat-controlled & possibly (Democrat + RINO) filibuster-proof senate?
Yes, you are in good company. Rush hinted at this on Friday when he talked about a McCain presidency.
