I’ve voted for the democratic party straight down the ballot every election for as long as I can vote. A major part of the problem is that the two party system guarantees that at some point republicans will get power and when they do, they drag the window to the right rapidly. When democrats get power, they’re comfortable with leaving the window where it is for the most part, insisting that we “work with republicans” while republicans never do the same. Compare eight years of Obama with four years of Trump.
