Now Barack Obama on a podium and slamming into Trump and "lets have a return to honest politics" - absolutely unprecedented in the history of US politics and Trump commenting that he fell asleep listening to the speech (he had to say something negative eh). It just indicates to me that there are two Americas, two separate polarised populations and the challenge for the Democrats is to attract a big majority of the US population and keep their support onside. The other associated move is to find a reputable leader who will be admired and respected in order to push on to better political position.
