The tough Senate map for Democrats is looking a little less tough

The tough Senate map for Democrats is looking a little less tough - Retaking the Senate in 2018 was always a tough climb for Democrats because they are defending 10 seats in states that Donald Trump won in 2016. But that difficult terrain is looking a little less daunting these days, as new polling has led some election forecasters to believe several of those states are actually quite safely in Democratic hands.
