WILKES-BARRE -- There is one week until Election Day, and the race for U.S. Senate in Pennsylvania is a tight one.
Republican incumbent Pat Toomey and Democrat Katie McGinty are waging the most expensive senate race in the country.
Nearly $120 million has been spent on the race between Toomey and McGinty in Pennsylvania, according to Federal Election Commission data compiled by the Center for Responsive Politics.
It's paid for an avalanche of advertising on the web, TV, radio, and more.
"Oh, just yet another one, and they keep going back and forth with only negative statements," said Allen Bonk of Wilkes-Barre.
"Anything I was doing was brought to a screeching halt and I'm reminded how gross politics are today," said AJ Krier of Wilkes-Barre.
"It is unprecedented," said Dr. Thomas Baldino, a political science professor at Wilkes University.
Dr. Baldino says the reason so much money is being dumped in Pennsylvania's senate race is because so much is at stake.
"We have a senate that could flip parties from Republican controlled to Democratic," Baldino said.
Most of the money to pay for the ads is not coming from Toomey's or McGinty's respective campaigns, it's coming from wealthy donors and political action committees, and many of the ads are attack ads.
"It seems to follow suit with the Trump/Clinton negative political ads," said Dr. Karen Mercincavage, mass media professor at King’s College.
Dr. Mercincavage has an entire class at King's studying the persuasion power of political ads. She says the ads that probably made the biggest impression on voters were those that aired months ago, earlier in the race.
"Now with the saturation of ads, it has less of an impact," she said.
