To be technically correct, he holds effective sway over about half of the population. The other half (those afflicted with TDS) will do the exact opposite of what he suggests. Ergo, his “net effect” approximates zero.
Uhm, a better way to put it is that 44% of the population is afflicted with Trump Blindness Syndrome, wherein anything Trump says or does, no matter how crazy or untruthful or against the norms of the American Presidency, is accepted as totally normal and actually good.
There is a mushy middle of people who vacillate about Trump.
Then, there is a hardcore group of people who see nothing good coming from Trump, like, ever.
As to the way he has handled the crisis, don’t look solely at when flights were shut down or when social distancing was or wasn’t implemented.
Look to where Trump stepped up with a national plan to get enough ventilators for each state when needed, to ensure PPE got to the right states at the right time, that the governors all agreed to the national plan for shutting down schools using the governors’ authority. Look for the national testing plan, the national plan to create tests and vaccines. Look for the Federal leadership coordinating our national response to the crisis.
That doesn’t exist. Trump is running this crisis like he’s run his businesses and how he’s run his presidency - pitting people against each other, having no long term strategy, always looking to make himself the center of attention. The Trump Presidency is like the Trump casinos in Atlantic City, like Trump University, like Trump Vodka, like Trump steaks, et al.
