Probably many Republican congresspeople and their supporters (including those on this board) will say they were just trying to protect the economy, and their opponents do not understand this. However, they have not protected the economy, they have harmed it. Had they fought the virus with reasonably intelligent measures, as other countries have done, the US economy would be in much better shape.

Probably many Republican congresspeople and their supporters (including those on this board) will say that other countries have actually not faired that well, but that claims of having reached a better situation with the virus are false information, or that they did not have so many people to contend with. But this is an exaggeration at best, and recklessly false information at worst. There is enough information out there now to have a pretty good sense of the most obvious covid19 battle successes, and some that are not successes but which are vastly better than the US situation.

based on the daily new cases chart, there is no end in sight for the US, and even though the medical community is fighting hard, it is fair to guess we will soon be starting to see a rise in deaths soon. The deaths chart also indicates that.

so, will we be moving toward 300k US deaths soon? 500k? More? Will the Republican legislators then start standing up to the monstrosity they have kept in office through their support? How about the folks here who have supported those legislators?

The Republican don't care about how many people die, they care about reelecting Donald Trump. Those who are running this year are concerned with staying in power themselves, if Trump loses and they win they'll take that. They still won't care that people die.
