Disagree on SoT. His biggest issue was delay in getting to OH. Supply chain issues were not his doing, nor the archaic technology leading to recent air issues. He's done a lot of good stuff with the infrastructure funding. A lot of the knocks are purely partisan attacks. The GOP leadership see him as a rising star, so a level of attack is expected.
My thinking on this is around executive positions, which is what POTUS is. Successful executives have strong cognitive ability, are excellent communicators, and have an ability to inspire others. POTUS also needs the ability to politic. Pete has the first two in spades. He has shown the ability to inspire - how do you think he came out of nowhere to be a top contender in 2020? He needs to grow in this space, but I believe he can. He also has the political skill, which continues to develop.
All the tools are there.
