When Donald Trump was President, there was a time when he had the house and the senate. Trump could have enacted a bunch of right wing legislation and the democrats couldn't stop them since they wouldn't have the votes.
Joe Biden is President now. He now has the House and the Senate. He can enact a bunch of left wing stuff. He could ban AR 15s and AK 47s in the entire country. He could enact his healthcare ideal right now. I don't want him to do these things, but he has the votes. Despite this, if he gets this done, it won't be for a long time. This is like this in every country in the world. Politicians are so slow.
Why are politicians so slow?
