When the Democrats can line up 500 Biden-festooned golf carts in The Villages to caravan over to the early polling station, it’s a sure sign the culture of the place has shifted. The massive retirement community is supposed to provide a reliable harvest of Republican votes that will help offset the GOP’s weaknesses in the cities and throughout South Florida. Photos of the scene must strike terror in the hearts of President Trump’s campaign, and it helps explain why Joe Biden is consistently ahead in surveys of the Sunshine State electorate.

The defection of older voters to Biden also has something to do with Lindsey Graham’s difficulties in South Carolina. Perry Bacon Jr. of FiveThirtyEight thinks Graham will probably survive, but that’s based on the historical reluctance of white voters there to even consider supporting a Democratic candidate. This doesn’t keep Democrats from getting 45 percent or better, but it does preclude them winning a majority. Yet, if white seniors crossover in even small numbers, the calculus changes. In the most recent poll of the race, Graham is trailing is challenger Jaime Harrison by a single point.

It’s not just white seniors, either, but white women in general regardless of their age. They’re abandoning Trump and it’s putting a lot of supposedly safely red seats in play, all across the Sun Belt and throughout the nation’s suburbs.

Winning elections is about addition, but Trump hasn’t added to his 2016 coalition. He still seems focused on boosting the enthusiasm of his diehard base, and that’s not worth nothing but it’s not enough when you’ve energized your opponents for four years.
