We all want reduced immigration, but the spikes are due to faulty data, not more Mexicans. Mexicans can get wrongfully counted as a valid “case” just like anyone else. The left is trying to fake-up the numbers without regard to nationality.
I think they are heavily testing that population. More tests mean more cases. Anecdotally, that population doesn’t seem to be down with social distancing and has a very high obesity rate, but I think it’s due to the increased testing.
