Was Trump's handing of Coronavirus a big factor in America's decision to elect J. Biden as President?

No.  There are more sinister reasons for Biden's so-called 'win'.

You've let yourself be played for a fool by the people you listen to for your information concerning SOME things about Trump his handling of COVID-19. 

First yes, there was a lot of blame on Trump for the effect of COVID-19 on the country. However, NO ONE has been able to yet explain just WHAT he should have done differently than he didn't already do with a rational, informed argument! For over a year there have been yappy little dogs nipping at his heels over it, but that's all they do. Not one has brought forth the definitive explanation of what he SHOULD have done differently!

Trump implemented restrictions on travel from China in January 2020. Liberals literally called him "racist" for doing so at the time. They were the ones who still hadn't got a grasp of the danger presented by the Chinese coronavirus yet, not Trump. More travel restrictions from other regions as well as other actions were implemented soon after. Trump has been ahead of the game from the beginning.

He kicked-off a bigger effort toward making a vaccine than anytime in American history, with government support (Project Warp Speed). Three are now being deployed. The perpetual Trump critics were crying that having vaccines this soon wouldn't be possible.

Trump deployed national assets around the country to help. This included Navy medical ships to the East and West coasts. The USNS Mercy was deployed to one of the nations hot spots, New York, where it sat mostly unused by Gov Cuomo and Mayor de Blasio!

The vaccines didn't start coming on-line until after the election, just WHAT more were people expecting him to do?! 

Trump NEVER called COVID-19 a hoax! That was a lie that someone started that the Liberal press never had the integrity to correct. So to was the bleach thing. Trump foolishly posed a off-handed question to his COVID task force in a public press conference if there was any sort of injections that could be used (he had ample opportunity to ask that in private as he should have. That's where brainstorming belongs). But there was nothing practical that was available. This got turned into his "suggesting people should inject bleach"!

People were angry at the mounting death toll. They felt/feel helpless and could only lash out at Trump, without ever asking what he should have done differently to have avoided all those deaths. Do YOU have an answer? If the people you listen to for your information have never given you one, ask why not.

Biden's "success" rests fully on the shoulders of what Trump made possible. He would be reaping the praise right now if he was reelected!

No, the only factor that got Joe in to office was the Coup committed by the DNC, China and Iran !

Trump not only won the Electoral College Vote  but he also won the Popular Vote in 2020 ! By approximately 11,000,000 Votes ! (T=~79Million, B=68Million) !

Even Anti-Trump Google Trend data agrees with Trumps assessment of popularity!

According to the corporate media it was.  Still there were coverups in Democratic states about their handling of COVID-19 and the media hasn't found any in Republican states or with Trump.

It was the key factor. Without Covid, Trump

Would still be President

Yes. In a crisis you need a leader who will deal with the crisis, not pretend that if he ignores it, it will just go away. 

Without a doubt. Have you ever seen the ads that The Lincoln Project alone ran during the campaign? They were great!

That probably was a big factor in why Trump lost, but the #1 reason Trump lost is his supporters, like the lying right-wingers like @David and @mustagme who have answered this question.

Yes, Trump save 2 million lives and Democrats got mad.  The original prediction was 2.4 million deaths.  They also got mad that he ushered in a vaccination in record time

Fraud put AntiPOTUS Biden in office. Nothing else. President Trump received the most legitimate votes in history.
