On the surface, President Joe Biden seems to be doing pretty well. But underneath, there are signs of problems, areas where partisan overstretch threatens the underpinnings of what some are hailing as the new order of things.

Biden enjoys 54% job approval, a good mark for a president at mid-term or facing reelection, but below the 100-day numbers of every post-World War II president except Trump. Biden’s 42% disapproval is higher than theirs and about equal to Trump’s. That may understate things if, as the Cook Political Report’s Amy Walter suggests, polls are undersampling Republican voters.
