Because it usually is because of republicans. I get that you are biased as hell, but at some point you have to look at the bigger picture and get a better understanding of how government works. This "we won, we are in charge, we should be able to do everything I want RIGHT NOW" shtick isn't as charming as you think.
Being a simp is even less charming.
Nobody made Biden open up public lands to drilling faster than Trump ever did, he did that all on his own.
Nobody made the Biden administration aggressively go after student loan debtors, even ones that managed to get out from their debt.
Nobody made the Biden administration restart Trump's remain in Mexico policy.
Biden can circumvent congress to make a cushy job for a crony, but can't get around an unelected bureaucrat that previous administrations ignored.
No, none of this is republican fault. Republicans may not provide votes in congress, but with no pressure on the democrats they don't provide votes either, and they seem perfectly fine with this. Mostly because they're banking on people like you, but that doesn't win elections outside of very extraordinary circumstances.
Because to circle this back around, we're supposed to vote against republicans because they hate transgender folk. Fair. Democrats could stop this or at least look like they're interested in stopping this, but aren't. So why vote for them?
