Do you have evidence that other politicians would have handled things significantly differently? As I said, the articles I found from the beginning of the crisis don't demonstrate that. Have you found any articles from, say, the beginning of February where politicians are calling for a much more robust response? The legislative branch certainly has the ability to act when they don't think the executive branch is up to the task (they actually were embroiled with a political battle with Trump at the start of this, but it was about impeachment).

Getting rid of Trump and replacing him with someone who would have handled this much better is great. Replacing Trump with someone who would have handled things about as well, keeping all the other political leaders who dropped the ball on this, and not changing the deep structural issues that have made things worse, will do little to help.
