Obama was personally popular, but his unpopular policies decimated the Democrat Party. Here are the stats according to Red State:
President Obama maintained very high personal approval ratings, while his polices were consistently rejected by the American electorate. As a result, his party lost over 60 House seats, 13 Senate seats, the majority of the governors races, and nearly 1,000 state legislative seats during his time in the White House.
Since Trump is personally not liked, but implementing popular policy, it will be fun to watch and see how this evolves over the next few years (at least when you’re a political geek 😊).
