Sorry, you will get big changes voting for Trump. becasue too much is already in place to make those types of changes happen. I dont agree with these changes, but to say they are the “same” is a dangerous opinion.
The person at the top is needed to green light policy… those lower down present such policy… While this can seem boring it is important, since while by definition the president will be at the center of their party. If the party you vote for is most interested in vetoing everything of the other party… even if they agree with the law in general, there is no progress.
Of course you must do more than just vote for the least bad president to make the change happen… However if you can’t at least do that you own the results os the OP said.
Do it in the primary… where the current system expects it… but… there is only 1 or 2 primary candidates in the current style winner takes all scenario we have… and ID say fight for instant runoff elections, but vote for those with a chance until then… Even if you think your state is safe…
