I'm not American. Maybe my opinion also comes from a place of not understanding how government works in the US. But in 2020, Biden won the Presidency and the Democrats had control of the House and the Senate. Yet, they had a harder time of reversing Trump's policies than he had pushing them through. Let alone not even trying to enact progressive policies.
As an outside observer, maybe that's why people have lost faith in the Democratic party.
What if he needs to make an international trip?
