Are you fucking stupid?
Democrats were in power
We have 3 branches of government. One that takes decades to change the makeup of. One that is split in two and tends to favor the number of states.
Any one of those branches can fight the other two and stop progress. The one that is split i two fights itself.
Currently, all 4 groups are controlled by Republicans. Two years ago, only 2 of the 4 were controlled by Democrats. Those are not equivalent sets of "in power".
