Judge rejects GOP effort to throw out 127K Texas votes

Biden and Lady Gaga, who is performing tonight at his drive-in rally in Pittsburgh, visited the University of Pittsburgh to greet supporters and student organizers.

They each thanked the volunteers for their hard work, with Biden adding his praise for the young supporters. 

"Thank you, thank you, thank you for all you're doing for us. By the way, you are the most incredible generation there is. For real. Z Generation and all -- all kidding aside, you're the best educated, you're the brightest, you're the least prejudiced, you're the most engaged and most open generation in American history. That's why we're counting on you," Biden said.

The Democratic nominee also joked about their joint event later, telling volunteers, "Lady Gaga's gonna be speaking and I'm gonna be singing."

In his second rally of the day and his last in the all-important battleground state of Pennsylvania, the president exuded confidence about winning Pennsylvania, declaring, "This does not look like a second-place finish.

"You know, we win Pennsylvania, we win the whole deal. You know that, right? Just like last time. We want to have the same result as we had last time," Trump said, though a new ABC News/Washington Post poll puts Biden with a narrow lead in the state Trump won by just one point in 2016.

As accustomed, Trump also went after Pennsylvania Gov. Tom Wolf, a Democrat, for having restrictions in place to prevent the spread of COVID-19, as cases and hospitalizations rise in the state. 

"Pennsylvania, get your state open. Get it open. Terrible. Terrible. Your governor has to open your state, Pennsylvania, has to open your state," Trump said to chants of "Lock Wolf up." 

He went on to address counting ballots in Pennsylvania -- after GOP efforts to stop mail-in ballots from being counted after Election Day were blocked last week -- and in a somewhat threatening tone said, "We have a lot of eyes on the governor" and "we got a lot of powerful eyes watching them." 

"So governor, open your state and please, don't cheat, governor. Please don't cheat. Because we're all watching. We're all watching you, governor. We got a lot of -- we have a lot of eyes on the governor and his friends. A couple of other governors out there too," Trump said. 

The president may have been talking about poll watchers or attorneys, but he didn't explicitly specify.

Sen. Kamala Harris participated in two get-out-the-vote events in Pennsylvania this afternoon, a canvass launch in Luzerne County and a drive-in rally focused on Latino voters in Lehigh Valley, as Democrats pour their efforts into the state Trump narrowly won in 2016 in their final full day of campaigning. 

In Luzerne County, Harris spoke to a crowd of 76 people about the importance of Pennsylvania to their path and told supporters there that Pennsylvania will determine the outcome of the election.  

"That's why we're all here and keep coming back -- because we care about Pennsylvania and because Pennsylvania's gonna determine the outcome of this election," Harris said. 

Without mentioning Trump by name, Harris also hinted at the president's threats of legal action following the election, describing them as efforts to suppress the vote and intimidate voters.

"We know that there are a lot of folks around the country, including you know who, who have been trying to openly suppress the right to vote, to intimidate, to make it difficult, to make it confusing," she said, telling supporters it's all the more reason to make sure their ballot is cast and counted. 

Vice President Mike Pence at an afternoon rally in Erie shared the senator's sentiment on the importance of Pennsylvania, telling his crowd of supporters that "the road to victory goes right through the Keystone state."

The former vice president, at his first of three events barnstorming Pennsylvania, shared his belief that "what happens tomorrow is going to determine what this country looks like for a couple of generations" and hammered home his "Scranton vs. Park Avenue messaging" for the union crowd.

"I've never forgotten growing up in a hardworking family in Scranton," Biden began. "The lesson that Donald Trump has never learned because he can only see the world from Park Avenue. He can't see what families like yours and mine have gone through. So he refuses to do the work to get this virus under control."

Biden ticked through his promises to reward work not wealth, and once again hit back at Trump on fossil fuels, saying he "never" said he would ban fracking.

"And by the way, no matter how many times Trump tries to lie about it. I will not ban fracking, never said I would. But I'm going to end Trump's incentives to send jobs overseas," Biden said. 

Biden also punched up his attack on Trump reportedly calling military service members "suckers" and "losers," according to reporting in The Atlantic, saying that it is Trump who is the loser. 

"The way he talked about our veterans being losers -- losers. What's this guy all about?  Who is he? He doesn't understand what's going on," Biden said, raising the service of his late son Beau, who was awarded a Bronze Star.

"He came home and he died of cancer but he came home and guess what? And guess what? He was no loser. Trump's a loser."

After he finished his remarks, Biden played the part of proud grandfather, bringing four of his grandchildren traveling with him on stage and adding, "They're proud to be here with you. I've been bragging about Pennsylvania."
