The die hard supporters, yes, but his approval is already in decline across a bunch of key demographics (women, independents, hispanics). The only President that has been less popular in the first 100 days is... Trump (first term). The majority disapprove with the current handling of the Ukraine war, ending foreign aid programs, and immigration (his strong point). His approval on the economy has fallen 13 points since December, which should be alarming for his party, as that was a key factor in his re-election (Biden inflation concerns). He can blame Biden all he wants, but the majority of Americans identify current economy as belonging to Trump. It's hard to blame Biden when he's been so vocal and brazen about the tariffs.
