I disagree. McCain has proven himself to be unmanagable, and he has repeatedly thumbed his nose at the US Constitution and the citizens of this country, as has Hillary.
Again, I offer that as bad as he can be (with much of his ill-will earned by his self-servance - which who knows, may be satisfied somewhat now that he is the 'big guy') - he may be more easily inclined/swayed to Repub values than those of the Opposition. Offer this because - as mentioned - despite his Liberal prostrations; McCain is no committed Leftist ideologist.
Beyond all that - most importantly and critically. . . our Military deserves a Commander-in-Chief who can and WILL respect them.
