The 2004 United States presidential election in Pennsylvania took place on November 2, 2004, and was part of the 2004 United States presidential election. Voters chose 21 representatives, or electors to the Electoral College, who voted for president and vice president.
Pennsylvania was won by Democratic nominee John Kerry by a 2.5% margin of victory. Prior to the election, most news organizations considered this a toss-up, or swing state. Although the Commonwealth of Pennsylvania voted for the Democratic presidential nominee in six subsequent elections since 1992, the margins of victory had become smaller over the past elections, with Republican Donald Trump carrying the state in 2016. On election day, Kerry won the state with 50.9% of the vote, but won only 13 of the 67 counties in Pennsylvania. Most of these 13 counties have the highest populations in the commonwealth. The biggest key to Kerry's victory was winning the County of Philadelphia with 80% of the vote.
Bush was the first president elected to two terms without carrying the Keystone State either time since Woodrow Wilson in 1912 and 1916. This to date is the most recent election where Pennsylvania would back the losing candidate who did not win the overall electoral vote, and presidency.

Al Gore won here in 2000 with barely 50% of the vote. In late October 2004, the state was split at 47% on whether or not to approve of Bush. But Kerry won the poll 48% to 46% in the last Mason Dixon poll.  Throughout the election of 2004, Kerry won most of the polls in the upper 40% to lower 50% range. However, Bush polled within the margin of error, usually in the mid 40% range. In the last Real Clear Politics average Kerry was leading with 48% and by almost a 1% margin. 
Bush campaigned heavily in the state and dropped by here over 20 times in 2004. But it wasn't enough to swing the undecided voters as Kerry won the state's electors with almost 51% of the vote, slightly higher than Gore.  
This Kerry victory can be attributed to the overwhelmingly Democratic cities of Philadelphia, Pittsburgh, and Erie. Although Kerry-held cities which voted for the Senator by narrow margins assisted him in advancing his margin over President Bush, many political analysts underscored the fact that if Philadelphia were excluded, President George W. Bush would have won Pennsylvania by a fairly slim margin, with 2,663,748 versus 2,395,890 for Kerry. Although Pennsylvania is closely divided in most elections, it did not vote Republican in a presidential election from 1992 to 2012.
Philadelphia and Pittsburgh were the biggest contributors to Kerry's victory in Pennsylvania. However, many independents in suburban Philadelphia counties (Bucks, Delaware, Montgomery, and somewhat in Chester) voted for Kerry, which may well have been the deciding factor. Kerry also had narrow margins of victory around cities like Allentown, Scranton, Erie, and the traditionally Democratic Pittsburgh suburbs; he also garnered many votes in certain rural areas such as parts of the Poconos and the Laurel Highlands, and in cities like Reading, Johnstown, Harrisburg, and State College. Bush's margins were extremely large in Central Pennsylvania and the sparsely populated Northern Tier, with traditional GOP cities such as Lancaster, Lebanon, York, Altoona, Huntingdon, and Williamsport strongly throwing their support behind him. This area, along with rural western Maryland, was clearly the most conservative in the Northeast.
As of the 2016 presidential election [update], this is the last presidential election that the Democratic candidate won any county bordering Allengheny County, namely Washington County, Beaver County and Fayette County. This is also the last election in which Dauphin County, Centre County, and Monroe County voted for the Republican candidate.

Technically the voters of Pennsylvania cast their ballots for electors: representatives to the Electoral College. Pa. is allocated 21 electors because it has 19 congressional districts and 2 senators. All candidates who appear on the ballot or qualify to receive write-in votes must submit a list of 21 electors, who pledge to vote for their candidate and his or her running mate. Whoever wins the majority of votes in the state is awarded all 21 electoral votes. Their chosen electors then vote for president and vice president. Although electors are pledged to their candidate and running mate, they are not obligated to vote for them. An elector who votes for someone other than his or her candidate is known as a faithless elector.
The electors of each state and the District of Columbia met on December 13, 2004, to cast their votes for president and vice president. The Electoral College itself never meets as one body. Instead the electors from each state and the District of Columbia met in their respective capitols.
The following were the members of the Electoral College from the state. All 21 were pledged for Kerry/Edwards.
