Donald Trump’s divisive and unpresidential demeanor is likely to gift the Democrats a big win at the 2018 midterms, asserts Jay Cost of National Review. While the investigation into collusion with Russia has yet to provide any evidence against the president, his handling of it has reduced voters’ trust in him. While he was legally allowed to fire James Comey, the way he went about it looked bad. His warm words about Russia in a Helsinki meeting with Putin also didn’t help. Americans like to see a president that is dignified and respectful. Trump’s behavior on Twitter and elsewhere has been everything but. This will be key during the midterms.
