This guy has no intentions of leaving if he loses, much less playing fair or legally. He will resort to every dirty trick in the book and write new ones. This is no schoolboy but a ruthless cutthroat dictator fighting for his throne.
I predict he will invent some 'emergency' to declare martial law, suspend Congress and "postpone" the inauguration of Romney if he loses the election. I'm sure at the very least he will get some crooked federal judge to issue an injunction delaying the transfer of power while he completes his coup.
If this guy doesn't scare you, check your pulse. BTW, it is your taxes paying for all his antics.
