After reassuring an enthusiastic crowd last Friday in New Hampshire that the Washington Post later reviewed the following facts: "This is the truth of God, my word as Biden."
Biden's misspeaks, error memories, and other gaffes are not the same as Trump's targeted daily attacks on the truth.
But they solve a debate about the nature of
truth in politics and how voters should differentiate between Biden's slip-up and the president's more serious habit of bending facts at historical tempo.
The cavalcade of lies expressed by the President has turned the traditional yardstick for judging a candidate's faithfulness to the truth and the consequences of such misconduct. However, the revelation of the President's habitual lie did not politically disqualify him. On the contrary, he often thrives by creating his own reality into which loyalists can shop.
As a result of this new era of destroyed facts, the 2020 campaign is taking place at a historic turning point.
Every word that candidates speak will be tested for falsehood by armies of media fact-testers as never before to face the challenges Trump poses.
But it's also a moment when the truth in politics appears more devalued than ever
The president's behavior has led many media commentators to argue that politics has entered a time after the truth ̵
And many Democrats argue that for Beltway experts it is a dereliction of duty to fix on Biden's verbal slip-ups when Trump seems to be tearing at the national structure.
"I'm a gaffe machine, but my god, what a wonderful thing compared to a guy who can not tell the truth," he said in Montana. "I'm ready to handle all these things, the question is what kind of nation will we become, what will we do, who will we be?"
Former Democratic presidential candidate Howard Dean said on Friday that Trump's serial falsehoods meant that mistakes by other candidates were taken less seriously.
"See, if voters can forgive Donald Trump for being corrupt and filling his own nest with money, they can certainly forget the few mistakes made by Joe Biden, and I think Trump has lowered the line bar So much … I think the rules of the game have changed, "Dean said on CNN's" New Day ".
Is Trump unique or is politics in a time after the truth?
 One of the main tests of the 2020 campaign will be whether Trump is unique and an outlier. Or has he created a leadership style that is not only invalidated by demonstrable facts, but can also be emulated by other politicians and has lowered the threshold of truth in public life?
How could Biden's airborne lies be exaggerated in the face of this new dynamic? and conflicts are assessed?
And should they undermine the central rationale of his campaign – that he is best able to beat Trump?
Biden is a particularly interesting test case. As a Democratic aspiring star, the then Senator folded his offer for the presidential nomination in 1988 over a plagiarism scandal.
It is a measure of how the standards of presidential policy have changed, that Biden's wrongdoing in the current era has not been so serious and the punishment has not seemed so definitive. The current president must withdraw from the race for plagiarism, because Trump According to the Washington Post, it has made more than 12,000 false statements in office. CNN's Daniel Dale reported Wednesday that Trump had made 48 false claims in the past six days.
Some Democrats have argued that Biden's gaffes are so typical that they are branded into his political image.
But there is also a clear double standard.
In Clinton's case, the lie reinforced the claim that she had a habitual problem with the truth.
The Post reported that Biden "got the time, place, heroism, type of medal, military branch and rank of recipient wrong, as well as his own role in the ceremony" in the story about the Afghan veterans ,
If Biden's story is not treated in the same way, there will be more than a touch of sexism.
Biden insisted on Thursday that there was no reason for the uproar.
"I pointed out how brave these people were, how incredible they are, this generation of warriors, those fallen angels we lost," he told the Post in an interview.
"I know not what the problem is. What did I say wrong? ?
A distraction for Biden
Every day that concerns the history of Gilde's Biden campaign is a bad day for his candidacy.
The Vice President presents himself as the Most Experienced and smartest democrat who can best be trusted to handle the negative barrage Trump is trying to trigger.
But self-imposed controversy undermines that argument and opens up the possibility of questioning Biden's attitude to the truth – which Trump becomes
The President has already asked questions about the age of the 76-year-old Biden, calling him "sleepy" and speculating on his state of mind – although Trump is also in his 70s.
Democrats toss The media reporting on Biden's gaffes are sure to avoid false equivalence, even though they claimed that the focus on Clinton's e-mails in 2016 was a vi ignored the worse behavior of Trump.
Unless you tell the truth about a critical state issue that affects the global economy, the clumsy merger in an election campaign certainly outweighs it.
However, nuances and proportions are repeatedly flooded during a presidential election campaign.
