(The Hill) Five Senate Democrats trail their GOP challengers and would lose their bids for reelection were the 2018 midterms held today, according to polls from SurveyMonkey.

New polls published Thursday morning in Axios show Sens. Claire McCaskill (D-Mo.), Jon Tester (D-Mont.), Joe Manchin (D-W.Va.), Joe Donnelly (D-Ind.) and Heidi Heitkamp (D-N.D.) would all lose reelection to GOP challengers if voters were heading to the polls this week.

With the exception of McCaskill, who is squaring off against Missouri Attorney General Josh Hawley (R), the senators were polled against generic, unnamed GOP challengers.
