A few weeks ago, Trump was dead and buried according to many in the media. As chronicled here, the DNC sprung an effective trap and the media piled on. However, Trump has gone back on the offensive. He has gone after Hillary on her crookedness and also on how the Democratic party has abandoned the blacks of the inner cities. This inner city assault in particular seems to have made Clinton nervous.
This push combined with Hillary's deepening email scandal has created a Trump surge. Several major polls show him closing the gap from double digits to medium or low single digits. This push has to worry the Clinton campaign who threw everything and the kitchen sink at Trump over the past month. They have to be wondering if their trump card of screaming racist is finally failing them. Trump still has ground to make up but it appears the momentum has swung his way once again.
