Wow. If this is true, let’s welcome President Elect John McCain to the White House!
Can a nominee of either party possibly win in the general when 20% in their own party votes for the other side? That’s a 10% swing (20% of essentially a 50/50 red/blue split) making it a 60/40 split, everything else held equal.
From where does this apparent 1-in-5 Democratic voter disenchantment come?
