It's an uphill fight for a Democrat, but if the economy slips at all, I think Arizona is in play. Besides Trump's cluelessness, crassness, and narcissism, I can't think of one proposal he has made that is truly popular. Repealing Obamacare failed in part because the Republican proposals were far worse than the existing law. Now it is tax reform, and again Trump and the Republican's proposals are at about 30%. Finally, if anyone is paying attention, Republicans have failed to govern. Despite having a majority in both houses of Congress and the Presidency, they have passed little meaningful legislation. If an election in 2018 is a referendum on Republicans ability to govern, they should be tossed.
