"Why did Obama campaign in Florida?"
He ran national ads that happened to run in Florida. That's it.
But they still ran there. And he didnt' have to run these ads and knew full well that they were appearing in FLorida. Why not wait until after the vote to run them?
Because the DNC said it was okay, and it's cheaper to run national ads than it is a series of regional ones.
Simple marketing reality.
Where did he get special clearance by the DNC? Did he ask for this clearance in advance? I never heard anything about this.
Yeah he got special clearance, didn't you hear about them checking his passport files??
because unlike Hillary he was thinking to Super Tuesday and beyond?
