Sen. Al Franken’s resignation puts another Democratic seat into the 2018 mix, but it’s still unclear whether his departure provides Republicans with a legitimate takeover opportunity.
To handicap a race, it’s helpful to know where the contest will take place and who is running. In this case, we know the place is Minnesota, where, despite Donald Trump’s surge in the Midwest, Hillary Clinton narrowly prevailed in 2016, 46-45 percent, and where Republicans haven’t won a Senate race since Norm Coleman’s 2-point victory in 2002.
