This should probably be getting bigger headlines but it is official now, 306 electoral votes have been certified for Joe Biden as of December 8th and 296 of those votes have met the safe harbor criteria. 270 electoral votes are needed to win so there is no way Congress can stop a Biden win January 6th.
From the AP: A deadline set Tuesday under federal law essentially locks in President-elect Joe Biden’s victory, even though President Donald Trump is still falsely claiming he won reelection.
Other than Wisconsin, every state appears to have met the safe harbor deadline, which means Congress has to accept the electoral votes that will be cast next week and sent to the Capitol for counting on Jan. 6. Those votes will elect Biden as the country’s next president….
Already one member of the House of Representatives, Rep. Mo Brooks, R-Ala., has said he will challenge electoral votes for Biden on Jan. 6. Brooks would need to object in writing and be joined by at least one senator. If that were to happen, both chambers would debate the objections and vote on whether to sustain them.
But unless both houses agreed to the objections, they would fail.
Democrats won the majority in the House again, so all Republicans plus a handful of Democrats would need to agree to throw out electors from all six swing states, so Trump can win 232 to 227.
Wisconsin has one lawsuit from the Trump campaign pending, all other states have dismissed them, so all states but Wisconsin met the safe harbor criteria which says Congress must accept their votes.
From WPR: According to Rebecca Green, professor of election law and co-director of the Election Law Program at William & Mary Law School, Wisconsin won’t qualify for the "safe harbor" deadline this year because of an ongoing state-level lawsuit brought by President Donald Trump seeking to overturn President-elect Joe Biden's victory in Wisconsin. That lawsuit, which was rebuffed last week by the Wisconsin Supreme Court, is set for arguments before a state circuit court on Thursday.
However, Green said Wisconsin voters shouldn’t be concerned their votes won’t count.
"If a state doesn’t complete any post-election processes by the 'safe harbor' deadline, that doesn’t mean its electoral votes will be thrown out or that Congress won’t accept them," she said. "It just means Congress isn’t obligated to accept them."
Green said if the slate of presidential electors certified for Wisconsin by Gov. Tony Evers on Nov. 30 is unchanged by ongoing lawsuits, she expects Congress to accept those presidential electors' votes.
Even if Congress ignored safe harbor status, they would likely be overruled by the Supreme Court.
From CBS News: The Electoral Count Act of 1887 determined that if a state certified its election results by six days before the Electoral College meets, then it would qualify for "safe harbor," and Congress must consider its results "conclusive." Every state except Wisconsin appears to have met the deadline, as there is a hearing in a lawsuit on the state's election results later this week. But Mr. Biden is still expected to receive all 10 of the state's electoral votes next week, since he won Wisconsin by around 20,000 votes.
Want more detailed data, like I did? You can start with the NY Times election certification tracker.
Personally, I like the National Popular Vote Tracker from the Cook Political Report but they appear to have given up tracking with four states left to go: California, Colorado, Hawaii, and Idaho are not set.
However, California certified December 5th and Idaho certified November 20th and both results are posted already at the National Archives. You can view the actual certificates of ascertainment here.
Colorado certified on time on December 8th.
From the Patch: Colorado Secretary of State Jena Griswold certified Tuesday the results of the 2020 General Election.
The certification was conducted after each county's bipartisan canvass boards submitted their official abstract of votes to the Secretary of State's Office.
As did Hawaii after finishing one last lawsuit.
From the AP: Hawaii on Tuesday certified the results of its presidential vote after the state Supreme Court dismissed an elections complaint challenging the entirety of the Nov. 3 general election in the islands.
President-elect Joe Biden won 63.1% of Hawaii’s vote, compared to President Donald Trump’s 34%, according to the final summary report from the state Office of Elections. Hawaii has four electors in the Electoral College, which is due to meet next Monday.
In other words, the votes are finally certified and beyond dispute everywhere but Wisconsin so even if members of Congress challenge the electors, from any other states, there does not appear to be any way Congress could vote to reject them due to the safe harbor clause. I’m sure the GOP will try, but there is a precedent for this, so it should not be that much of a concern. In 2004, Democrats objected to the votes from Ohio but both chambers voted to accept the electors from Ohio. Assuming that any challenges are raised on January 6th, with safe harbor, they will fail.
