A lot of American Christians aren't hyper committed to the specific theology of whichever flavor of Christianity they belong to, and will often sort of mix and match their own personal beliefs with what is orthodoxy.

That said, I'm ex-Catholic, so I don't feel super qualified to make a statement on the specific popularity of predestination among American evangelicals at the moment.

That said, in a less theological and more metaphorical sense, it does seem that many of them do believe in some sort of "good people" and "bad people", where the "bad people" are not particularly redeemable. It feels a little unfalsifiable though.
