Because they can't beat Clinton. How does the sound of President Hilary Clinton sound to you? How does the thought of Bill Clinton in the White House for 4 more years sound to you?
Think about that. Let it sink in. Meditate on it. Ponder it. Pray over it.
Then be afraid, be very afraid and then you'll know who to vote for.
So fear is to override guiding principles? How Conservative is that?
