@SmudgeTheInsultCat from what I hear from conservative media, Republicans have been feeling like fiscal responsibility has taken a backseat on their priority list behind a lot of other issues they have with the directions the institutions have gone for a while now.
They feel like they'll talk about fiscal responsibility after they first sort out things like their perception of corruption in the government.
Also: Harris doesn't make a good case for fiscal responsibility anyway, neither in her track record nor in her campaign promises.
So it's a loser coming and going. Republicans don't really care about fiscal responsibility at the moment, and even if they did Harris wouldn't be the candidate for that.
