Both have said little publicly, if anything, but are active behind the scenes.
Here’s a look at the landscape:
The most prominent Republicans already running are conservative commentator Kathy Barnette, real estate investor Jeff Bartos and Carla Sands, Trump’s ambassador to Denmark.
Of them, none has won elective office before, and only Bartos has run statewide in Pennsylvania.
Bartos is perhaps best-known to party members after winning the nomination for lieutenant governor in 2018 and running with gubernatorial nominee Scott Wagner on the unsuccessful ticket.
He also declared for Senate earlier than the others.
“Jeff Bartos is way ahead of everybody else,” said Jackie Kulback, chair of the Cambria County Republican Party.
Bartos, she said, has a campaign point person in every county, has visited every county and has campaign offices open all over the state.
One of the head-scratchers for Republicans is the influx of candidates who, until recently at least, did not live in Pennsylvania.
The more important qualification, it seems, is that they are rich.
