Five Senate Democrats would lose to a Republican candidate if the election were held today and three have approval ratings under 50%, according to new Axios/SurveyMonkey polls.

Why it matters: Democrats are defending 10 Senate seats in states Trump won in 2016. In six of those states Trump’s approval is higher than 50% (compared to 43% nationally). These numbers underscore how hard it will be for Democrats to pick up the two seats needed to win the majority despite Trump’s troubles.
