Take it for what it is worth but a new poll conducted in Pennsylvania by a GOP PAC is indicating President Trump has a 4 point lead over Joe Biden.
  More people identifying as Republicans were given the poll and even with that skew the handling of the coronavirus by the Trump admin was viewed unfavorably.

However, President Trump's approval numbers have held steady throughout the crisis and more people trust Trump with the economy over Biden.

It is early in the process still, but these numbers could be viewed as a positive sign for Trump's reelection as November approaches.
