Who's voting,for whom and where? US election analysis talk

The next concrete vote on Trump isn't until November, but pollsters and election wonks are all analysing the data furiously to see if the Democrats will ride a wave back to congressional power, or whether Trump and the Republicans will in fact be able to dig down further and secure a counter-cycle triumph.

This election analysis and discussion from Politico is fascinating and a must read for students of American politics.
