Trump STILL claiming: "This is a fraud on the American public." "It was a rigged election. We're still fighting it." "We won by historic numbers." "We will never give up. We will never concede." "We will 'Stop the Steal.'" "When you catch somebody in a fraud, you're allowed to go by DIFFERENT RULES."

Al Gore?  Concession speech was six weeks AFTER the election? How about Hillary telling Joe Biden not to concede if he loses, and that she wished she had not conceded.    

His concession came after weeks of recounts and court cases that needed to play out. Once the Supreme Court ruled (in error) Gore conceded.
And we got that supreme Republican mediocrity, Dubya, who dragged us into an illegal and unnecessary war.

December 13 to November 7 = five weeks, one day. Or were you using "six weeks" metaphorically, like DeSantis and his "slit their throats" boast?

and counted backwards.  Lol

was six weeks.  He put a question mark at the end of the sentence.  I'm sure he was VERY confused because you put December before November so all he could do was take a wild guess.

Gore waited until the sixth week to concede. Aren’t you just splitting hairs here?

Gore pursued legal means to challenge the extremely close Florida vote. I am adding CAPS or *** for emphasis in some passages.

2000 United States presidential election recount in Florida.
"The 2000 United States presidential election recount in Florida was a period of vote recounting in Florida that occurred during the weeks after Election Day in the 2000 United States presidential election between George W. Bush and Al Gore. ..."
.
"The Florida election was closely scrutinized after Election Day. Due to the narrow margin of the original vote count, Florida Election Code 102.141 mandated a statewide machine recount, which began the day after the election. ..."
.
"Once the closeness of the election in Florida was clear, both the Bush and Gore campaigns organized themselves for the ensuing ***LEGAL process.*** ..."
.
"Following the machine recount, the Gore campaign requested a manual recount in four counties. ... The manual recounts were time-consuming, and it soon became clear that some counties would not complete their recounts before the deadline. On November 13 the Gore campaign and Volusia and Palm Beach Counties sued to have the deadlines extended. ... Meanwhile, the Bush campaign worked to stop the recount. On November 11, it joined a group of Florida voters in suing in federal district court for a preemptive injunction to stop all manual recounting of votes in Florida. ..."
.
"As the manual recounts continued, the battle to certify the results intensified. ..." [the "battle" was a LEGAL, NON-VIOLENT battle that took place in the courts, not in the streets].  
.
"As the manual recounts progressed, most of Florida's counties were considering overseas absentee ballots. ... The next day, Gore sued under Florida's statutory construct of the "contest phase". ... On December 8, the Florida justices, by a 4–3 vote, rejected the selective use of manual recounts in just four counties and ordered immediate manual recounts of all ballots in the state where no vote for president had been machine-recorded, also known as undervotes. ..."
.
"The U.S. Supreme Court convened on December 1 to consider Bush's appeal. On December 4, the Court ordered the Florida Supreme Court to clarify its ruling that had extended the certification date. On December 9, the Court suspended the manual recount, in progress for only several hours, on the grounds that irreparable harm could befall Bush, according to a concurring opinion by Justice Antonin Scalia."
.
"On December 12, the same day as the U.S. Supreme Court ruling, the Florida House approved awarding the state's electoral votes to Bush, but the matter was moot after the Court's ruling. Some have argued that awarding the electors in this manner would be illegal. ..."
.
"On December 13, Gore conceded the election to Bush in a nationally televised address."
.
http://en.wikipedia.org/wiki/Al_Gore#Recount
"... The Florida recount was stopped a few weeks later by the U.S. Supreme Court. In the ruling, Bush v. Gore, the Justices held that the Florida recount was unconstitutional and that no constitutionally valid recount could be completed by the December 12 deadline, effectively ending the recounts. ... On December 13, 2000, Gore conceded the election. Gore strongly disagreed with the Court's decision, but in his concession speech stated that, "for the sake of our unity as a people and the strength of our democracy, I offer my concession."
.

pending in 2020 as well.  At the time, there are issues pending litigation.  Why were the Dems in such a hurry to finalize things?  Why wasn't Trump given the same courtesy as a sitting President that Gore got when he was only a sitting Vice President.  Even though Trump eventually lost all of his challenges, Biden had already been installed as President.  If they had let it play out, and then handed over the Presidency to Biden, there wouldn't be so many people still questioning the results to this day.  Was it because the fix was in on the Hunter Biden coverup and it might unravel any minute?  Hopefully, we will know before the 2024 election.

that the "+1 day" falls into the sixth week even after conceding that it's five weeks and a day.  Gore waited until the sixth week began, so it would be untrue to say it was five weeks, since five weeks had already elapsed.  You'd think a stickler for details like Impposter would know this.  

CDL originally said, above, "How about that  ... [Al Gore's] Concession speech was six weeks AFTER the election?"
.
5 weeks + 1 day = 5 weeks + 1/7 week = 5.14 weeks. Rounding to weeks, 5.14 weeks rounds to 5 weeks, not 6 weeks.  
.
CDL could have said "36 days" or "5 weeks and 1 day" or rounded off 5.14 weeks to 5 weeks. CDL wanted to make the time between the election and Gore's concession appear longer than it was. By CDL's reasoning, I'm surprised he didn't round off 36 days = 1 month + 6 days to "two months."  
.
BOTTOM LINE: Gore accepted the court rulings and "for the sake of our unity as a people and the strength of our democracy, I offer my concession."

Imp, I don’t want you to think we here at P&R don’t appreciate the detail and breadth you often bring to a discussion here, but maybe take a step back this time and see how it looks?

...white knighting for CDL so much.  You come off like Liddle Lindsey Graham who constantly white knights for Trump.  It's not a good look.

predicted that he would double down on claiming it's not six weeks even though he stated himself that the sixth week had already begun.  I did not say originally that six weeks had been COMPLETED, I just said he waited six weeks to concede, and it was indeed during the sixth week that he conceded, not during the fifth week or the seventh week.  Will Impposter double down again?  It's anyone's guess.  I don't have a copyright on "I stand corrected", so maybe he should just say that and move on?
