So this is the end of the election, right? Not quite.

Despite President-Elect Joe Biden declaring victory last week, and his lead in Pennsylvania growing to 42,539 votes as of Sunday evening, President Donald Trump and his supporters are not conceding anything.

Trump loyalists rallied at state Capitols throughout the country, including Harrisburg, where armed militia members faced off against jubilant Biden backers over the weekend. And then there are the lawsuits.

Trump's legal team, led by former New York Mayor Rudy Giuliani, is promising a volley of new lawsuits in swing states this week. And there is a case pending before the U.S. Supreme Court over late-arriving ballots.

Amid it all, however, there has so far been no indication that any of the challenges — if proven to have merit — involve enough votes to change the outcome of the election.

THE CONTEXT: There are still a number of ballots that need to be processed and counted.

County election officials worked throughout the weekend to process upwards of 100,000 provisional ballots — those cast when a voter's eligibility is somehow in question. These are time-consuming ballots to begin with, and the number spiked this year because of the expansion of mail voting.

According to the Department of State, there were still another 54,000 mail ballots to be counted as well. County election officials owe results to the state by Nov. 23.

Some of the legal challenges have already been resolved. A suit brought by Republican candidates and voters asking for so-called "cured" ballots to be set aside. Instead, as Spotlight PA reported, a Commonwealth Court judge said these votes could be counted if they are found to be eligible through the normal process counties use to verify provisional ballots.

Looming is a possible intervention by the U.S. Supreme Court to throw out a state Supreme Court ruling that allowed counties to accept and count mail ballots that were sent by Election Day and arrived by 8 p.m. Friday. SCOTUSblog breaks down the possibility the high court will take on the issue, though, again, it's unlikely the number of votes in question would affect the election's outcome.

And finally, there's the possibility of a recount. While the current margin of Biden's win over Trump is too high to trigger an automatic recount, one could still be requested. And it seems certain Republicans will push for one.

"All of the uncertainty that was pointed out before the election continues today and may continue until the last votes are counted."
