New poll shows Tester losing by double-digits

Five Senate Democrats would lose to Republican candidates if the elections 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 that President 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.

The most vulnerable senators are Joe Manchin of West Virginia, Jon Tester in Montana and Claire McCaskill in Missouri. Each of their approval ratings is either under 50% or just above it, while Trump’s is well above that in all three states.

The least vulnerable senators are Bill Nelson of Florida, Bob Casey of Pennsylvania, and Sherrod Brown of Ohio. Trump’s approval is at just 46% in Florida and Pennsylvania and 54% in Ohio.
