Further to what Val said: Why don't you compile a list of all the train derailments since 2016 and show how many Trump attended and how many Biden attended. There are probably more than 100 train derailments, huh?It's the proper presidential thing to do. A similar analogy is when Biden, didn't go to East Palestine, Ohio, during the train derailment. If the tragedy doesn't involve citizens in Biden's voter demographic, then Biden won't attend.
Going to the sites would be almost a full time job.
