The 2 party system almost always creates a national equilibrium. Lagoa would be a remarkable choice. She was recently confirmed by the Senate with 80 votes. I would hope there would be a similar vote for her regarding SCOTUS.If the GOP ever gets the upper hand again. The way the demographics of the country are changing, including the natural forces of aging/death, exacerbated by COVID, the country is progressively (no pun intended!) trending more liberal and less conservative/GOP.
As an aside, I think that Trump selects Barbara Lagoa as his nominee, that will help him in Florida, a key battleground state.
