Pennsylvania is a state located in the northeastern part of the US. It was founded by William Penn in 1681 and it is one of the 13 original colonies. The state of Pennsylvania had an important role in the American history, as in its largest city – Philadelphia - took place many historical events such as the first and the second Continental Congress, the Declaration of Independence and many others.

Not only did Pennsylvania have a significant part in the past, but it has managed to keep its importance even nowadays. Since it the 5th most populous state of the US, it has 20 electoral votes and therefore is considered to be a swing state. This means that both parties try to make the best of their campaign here as winning this state could help them win the overall election.

Since 1992 to 2016, Pennsylvania backed the Democratic Party. However, in 2016 Donald Trump was able to win this state thanks to his campaigning in more rural areas, and by that targeting counties, where is the majority of white people with lower-income households and without any college education. Joe Biden won Pennsylvania by aiming for densely populated centers like Philadelphia and Pittsburg, and by getting support from black voters, who are the core supporters of the Democratic Party.
