>> mark county council has invested heavily in the millions of dollars and helping us prepare to meet the new burdens of pennsylvania have mail-in voting ballots. so, we've bought a high-speed letter opener, we've had several high-speed scanners, we really made investments in our election infrastructure to make sure that we cannot only be accurate but fast. >> and one thing that we heard from this official. in the nearby lehigh county. here's what we've seen in the past. as is a lot more democrats. about three times as many democrats requested mail-in ballots as republicans. so fetterman's campaign is already warning supporters, coming on a memo, saying the looks and results can take a while to shake out here. you could see it appears that there is a wet mirage they've called it. there could be democratic votes that are mail-in votes. then being counted later. of course, pennsylvania is a state where they're not allowed to open those mail-in ballots. until 7 am. when the polls open.
