Doug Mastriano: is the Trump-backed election denier too extreme to win?

The far-right Republican, running for governor in Pennsylvania, has extremist views - and he hasn't softened his positions one bit

As Pennsylvanians prepare to vote for their next governor, it is no exaggeration to say the future of American democracy is at stake.

Doug Mastriano, a retired army colonel who has enthusiastically indulged Donald Trump's fantasy that the 2020 presidential election was stolen, is the Republican candidate. If he wins, he plans to deregister every single one of Pennsylvania's 8.7 million voters. In future elections, Mastriano would choose who certifies - or doesn't - the state's election results.
