Democrats have been reluctant to politicize the pandemic by blaming Trump too openly for its virulent spread in the US, making us 4x more affected (and infected) than any other nation.
I think they will need to.
Trump's supporters -- who remain supporters of Trump through every indignity thrown at them -- need to understand it didn't have to be this way. When the second wave of deaths peaks just before the election, the Dems need to point out the science that argued against reopening too soon. They need to pin the blame squarely on Trump and the Republican governors who have placed profits above lives.
There is ample footage of the president making an ass of himself. "The virus will disappear like a miracle." "We have 15 cases which soon will be going to zero." When we have several hundred thousand dead, all they need to do is run these clips over and over and over again, with the tag line "Can we afford four more years of this idiot?"
I hope Tom Steyer and Mike Bloomberg follow through on their promise to fund anti-Trump ads in the Fall. Frankly, I think we need to start running them now, to limit the damage.
