Yes, he is the best I've found. This proposal is still at least an order of magnitude more testing though :) (on the order of 100 million tests/day, not 1 million tests/day)
Romer has called for as much as 30 million tests a day, which I think was based on some simplistic modeling. I think he was targeting everyone in the US being tested every two weeks. I think the two approaches are similar: let's test lots of people all the time, however many X million tests a day that is, so that we can quickly isolate and treat them. People are spreading it before they know they have it, so let's just test everyone all the time and not wait until they have symptoms.
