I think Trump’s support is widespread but thin. We are already seeing polls showing DeSantis either gaining on Trump or passing him up. And we are hearing Republicans being openly critical of him. Also, I look back at the rally in PA shortly before the election. They scanned the audience towards the end while Trump was still speaking and one could see many had left and those that remained looked bored
It's PA, they voted for Fetterman there. There must be something in the water.
