Nine of the 10 states that have seen the most rapid increase in coronavirus from Monday to Thursday are states that voted for Trump in 2016, led by Texas, where the number of reported cases increased by 297 percent.
On average, states that voted for Trump saw a 119 percent increase in cases over this 3-day period, as compared to an 88 percent increase in states that voted for Hillary Clinton (plus the District of Columbia). Weighted by state populations, the difference is slightly larger: 141 percent in states Trump won and 88 percent in states Clinton won.
For now, states Clinton won do have considerably more total reported cases. As of Thursday, Clinton states had 4.29 positive tests per 10,000 people, as compared to 1.13 per 10,000 people in Trump states. A lot of that difference is attributable to New York; without New York, Clinton states have 1.89 cases per 10,000 people.
