Pennsylvania could decide the White House race; what the polls say now

Seven swing states will likely determine the next president of the United States on election day - especially Pennsylvania.
Most states consistently vote blue or red such as the 38 states that voted for the same party over and over between 2000 and 2016, but some lean differently in each election. These battleground states of Pennsylvania, Arizona, Georgia, Michigan, Nevada, North Carolina, and Wisconsin are swinging so close that it can really go either way.
Pennsylvania holds the largest number of electoral votes and is considered essential to winning the White House, with both former President Donald Trump and Vice President Kamala Harris hoping to sweep up the state’s 19 electoral votes on Election Night.
The state's electoral votes have been given to Democrats in the last 7 out of 8 elections dating back to the election of 1992, the sole Republican vote went to Trump in 2016.
Pennsylvania's presidential voting record has proven, if anything, that it is very closely divided when voting between between democrats and republicans.
Over the past 200 years worth of elections, the Keystone state has cast their electoral votes for 26 republican presidential candidates and 20 democrats, with a success rate of 83% in casting for the winning president.
Here is what the Pennsylvania polls, odds say now — compared to the national polls and odds — as we head into Election Day on Tuesday, Nov. 5.
