MONTPELIER, Vt. -- I'm not surprised at all of the Obama Administration keeping tabs on the Trump campaign. It's the presidency, folks. You think Obama was going to leave his legacy, or the office in the hands of the Clinton's?! No way. It's hard ball.
The man was a two-term president - you don't get there by not knowing how to use dirty tricks; to mess with the opposition in nasty ways.
All the "Donald Trump will never be President" asides; Obama was determined to make sure that didn't happen. And obviously he and his team were very worried Trump could indeed win.
