There are a few "conservatives" that are suffering from BDS as well but I sort of believe that "they went from us because they were never of us"
Two thing, domestic policy involves congress, the courts and a whole lot of checks and balances. The Presidency is a minor part of that. But when it comes to foreign policy the President is THE only player that matters.
Second is that domestic missteps are painful and costly to clean up but they are not bloody. Foreign policy missteps are very bloody to clean up.
Most of the war we are in right now was caused by letting a democrat run foreign policy.
Good points, which is why I think the majority of the disgruntled conservatives, and I'm "among 'em, Pee Wee," as Dizzy Dean used to say, will put national security over border/spending/prescrip drugs in the fall. There simply is no alternative.
