According to Politico, “the GOP has seized on their uptick in party members as a sign that Trump is on track to win this critical Rust Belt swing state a second time”:
The GOP has also seen a larger boost in registrations than Democrats in three critical areas across Pennsylvania: Erie, Luzerne and Northampton counties, all of which helped Trump flip the state by backing him after supporting former President Barack Obama in 2012.
In 2016, Trump defeated Hillary Clinton in Erie County by 1.6 percent, Luzerne by 19.3 percent, and Northampton by 3.8 percent. By contrast, Barack Obama defeated his challenger Mitt Romney in Erie County by 16.9 percent, Luzerne by 4.9 percent, and Northampton by 4.5 percent.
Gloria Lee Snover, chair of the Northampton County Republican Party, said that people are telling her that they “want to be in the Trump party.”
