Election 2020 updates: Biden warns of 'dark winter,' pushes masks in pandemic plan

From Rodeo Drive in Beverly Hills to Fifth Avenue in Manhattan, police and store owners said they're preparing for Election Day unrest despite authorities coast to coast saying they've received no credible threats.

Some cities were bracing for the type of violence and looting that occurred earlier this year during protests that followed police-involved killings of Black Americans.

Stores along Rodeo Drive were seen with boarded up windows in the waning hours of the presidential election, with the mayor saying the street would be closed to vehicular traffic as an extra precaution.

In New York City, the sound of buzzsaws and hammers drowned out honking cars and sirens as work crews with truckloads of plywood swooped in. Along Fifth Avenue in Manhattan, near Trump Tower, workers spent Monday night boarding up the windows of some of the nation's most expensive stores, including Bergdorf Goodman and Saks Fifth Avene and nearly every shop in Rockefeller Center.

Similar scenes were found in Chicago, Washington, D.C., Atlanta, Denver, Philadelphia and St. Paul, Minnesota.

U.S. financial markets rose sharply today, achieving their second-biggest Election Day rally after 2008.

The Dow Jones Industrial Average climbed 555 points, or 2%, by the time markets closed. The S&P 500 closed up 1.8% and the Nasdaq spiked 1.9%. 

Hopes that there will be a decisive victor soon and not a long, drawn-out battle, helped drive the rally. Many investors said they are bullish on the idea that there will be clarity sooner rather than later.

Sentiments around elections on Wall Street can cause financial markets to swing wildly. Historically, the stock market was closed on Election Day in the U.S. through 1980.

Vermont Gov. Phil Scott, a moderate Republican, told reporters this afternoon that he voted for Joe Biden for president.

Scott, who is running for reelection against Democratic Lt. Gov. David Zuckerman, is a regular critic of the White House but had not publicly announced his intention to vote for Biden prior to Election Day, though he did say back in August that he wouldn't be voting for Trump. His moderate Northeast counterparts -- Larry Hogan of Maryland and Charlie Baker of Massachusetts -- wrote-in Ronald Reagan and left the presidential spot blank, respectively.

Sen. Kamala Harris made two stops in the Detroit area Tuesday as part of a last-ditch effort to get out the vote in the battleground state where Trump narrowly won in 2016. 

Harris' first stop was a canvass kickoff at Union Hall in Southfield. Harris thanked the 120 people in the crowd and spoke about the importance of Michigan and encouraged those to vote for Democrats down-ballot. 

“Today is the day that the path to the White House runs right through this hood, right through Michigan,” she said.

Harris gave a version of her stump speech, framing Donald Trump as incapable of handling the pandemic, economic downturn and race issues.  Lawmakers Rep. Brenda Lawrence, Sen. Debbie Stabenow and Sen. Gary Peters were all in attendance. 

Harris' second stop was outside of a church in Detroit where she greeted a much smaller crowd.

“You know, in Michigan, the last election for president, in 2016, the outcome of that election was decided, on average, by two votes per precinct in Michigan, two votes,” Harris said. “Can you imagine if each of us just pulled out another two people to make sure they voted today? That could determine who will be the next president of the United States of America.“

Harris has now boarded her plane and is en route to Wilmington, Delaware, for the campaign’s Election Night event.
