Trump, Harris campaigns make Pennsylvania most expensive battleground, spending $538M combined: report

More than $538 million in advertising dollars spent by former President Trump and Vice President Harris' presidential campaigns and their allies have been poured into the critical battleground state of Pennsylvania ahead of Election Day, according to a new report. 

The figure comes from an analysis published by the Philadelphia Inquirer on Tuesday. 

That makes Pennsylvania, which has 19 electoral votes considered critical to securing the presidency, the most expensive battleground state. According to the analysis, Democrats spent more than $294.7 million in Pennsylvania, and Republicans spent $243.6 million. 

Both campaigns and their respective allies spent about $185 million - or 52% - more collectively in Pennsylvania than the second most expensive swing state of Michigan, according to AdImpact. 

The top presidential candidates and their running mates have visited Pennsylvania 76 times since January, the Inquirer reported, though that jumps to 90 when including the stops President Biden made before he discontinued his re-election bid and endorsed Harris in July.
