re: Obama was democratic legislative seat wrecking ball during his 8 years

His approval rating is a total farce. I don't buy it's that high and if I learned anything from this election it's to not believe a damn thing you hear. The problem with the rating is it gets muddled with likability. Obama the personality is well approved of but Obama the President was a total disaster. The massive losses for Democrats like the OP referenced and the fact that he was so shitty that someone like Trump rose to power are undeniable facts the Left needs to come to terms with about Obama.
