Not just old people, but also less educated people... some might call them "rednecks". My brother, for example, still gets nearly all of his news from TV news and the newspaper. He has a flip-phone rather than a smart phone, and avoids the internet almost entirely (using it only for suppliers that require internet ordering).

He's relatively uneducated, having only a high school diploma (and he barely got that) but he's also quite successful, running a business doing specialized repairs to heavy construction equipment with a revenue over a million dollars/year.

And he's a die-hard republican who thinks Trump is just what this country needs.

And old people .... Vote.
