Technically, all adult Catholics can become Pope. But realistically it's just one of the cardinals, which means you need to become a bishop first, which means you need to become a priest first, which means you need to be celibate (x). This guy has a wife, according to the article, so he cannot become a Pope.

(x) this is technically not true for some Anglican orders that later became Catholics? Maybe? (I never remember the rules of the ordinariate.) So maybe he could first become a priest in Anglican Church, then switch to Catholicism, then become a bishop, then a Cardinal, then a Pope? It's a long shot though.

edit: ahhh the married priests in Ordinariate cannot become bishops. So he would need to have first his marriage annulled I guess.

While this is for practical purposes true _now_, there actually were a small number of married popes (https://en.wikipedia.org/wiki/List_of_sexually_active_popes#...), and there have been a few popes who were not priests before being elected (if you want to be pedantic, Peter wasn't a priest, and may have been married, but there were later examples).

> all adult Catholics can become Pope

All adult male Catholics, though also see Pope Joan (probably didn't actually exist, but was generally believed to have existed until quite recently). There's also no actual age requirement, though in practice the youngest pope was _probably_ 18.

Adult male Catholics, surely?
