Republicans in the Hudson Valley say President Donald Trump's COVID-19 diagnosis is a game changer, and could affect his presidential campaign just a month away from Election Day.

Republican strategist John Murtagh says that past presidents have been hospitalized before, but not this close to an election.

Several other of Trump's key advisers have also tested positive for COVID-19 and are in quarantine, like Kellyanne Conway, campaign manager Bill Stepien and former New Jersey Gov. Chris Christie.

Murtagh says virtual events are just not the same as packing a stadium or convention hall like Trump prefers. He believes the president's diagnosis might open up some cracks in his base.

Republican strategist Jason Meister, however, says people actually may support Trump more as he overcomes the virus.
