Why is Trump running as if he's not president and will fix all the problems happening during the current presidency, whoever that is?

"No. I don't take responsibility at all." - None of it is Trump's fault.

Trump closed travel from China and only let 40,000 people enter the US from China after the "travel ban".

He cut taxes for the wealthiest Americans because no one has ever been hired by a poor person.

He countered Obama's destruction of the economy by doing everything in his power to get the economy back to where it was when Obama took office.

He had to start from scratch to develop COVID-19 test kits because Obama didn't leave him any.

He repealed and replaced Obamacare with a plan that covers every American with better coverage and lower deductibles at a fraction of the cost ON DAY ONE just like he promised.

He Built a wall along the southern border and Mexico paid for it.

He balanced the budget and cut the deficit in half.

He saved the lives of every American who hasn't died from the coronavirus yet.

He has brought Americans together and ended racism.

He has never told a lie.

He won the easy trade war with China.

He ended North Korea's quest for nuclear weapons and made them one of our closest allies.

He gained the respect and adoration of our western allies that Obama destroyed.

I could go on and on but the point is Trump is the greatest leader in world history.

Your question doesn't make any sense. Trump has fix any number of problems in the past 3 years and those that have lingered on for decades. What Trump has done in the last 3 years is turn the economy around, turning it into the strongest economy the country has seen in the last 15 years if not longer (prior to COVID-19), including the lowest Black and Hispanic unemployment on record (again pre-COVID).

His policies allowed the US to become energy independent. This has been due to opening up more area for oil drilling, fracking and some coal production. Resulting in low energy and gas prices. Drawing more companies back to the US because of that.

As the economy reopens, he will apply many of those same economic principles to get the economy humming again (hint: Supply-Side economics. Something that was lost on Obama for all his 6 years of "recovery" from 2010 to 2016) as necessary. He has taken on tough problems other presidents kicked the can down the road on for decades. This includes illegal immigration. It includes trade issues with China on issues like American intellectual property, trade imbalances and too much dependency on them in areas like manufacturing, this now on full display due to COVID-19. He pushed through a major new US, Canadian, Mexican trade partnership (USMCA), eliminating a number of problems with the old one (NAFTA). He has taken a very visible stance with the pro-life movement. He has continued the fight on terrorism. He has not been afraid to take the fight to the sources of terrorism either, like Iran. He's been key in brokering a historic peace deal between Israel and the UAE. All without needing to drag Palestinian issues into it.

Even though the economy, the stock market and American lives in general have taken a serious hit from the coronavirus. The economy is still fundamentally strong thanks to Trump's work over the past 3 years. The market is starting to come back. Although some stocks will be legitimately adversely effected for the near future due to supply chain and travel issues. Even then the travel industry showed greater improvement that expected recently. This fundamental strength is what will help it recover. States are also slowly starting to let business reopen. This, is unlike the crash of 2008, where the economy had systemic problems that needed massive fixing before it could recover.

As for COVID-19, Trump implemented restrictions on travel from China in January. Liberals literally called him "racist" for doing so. 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. There has been a bigger effort toward making a vaccine than anytime in American history. One may actually be ready this year, faster than expected with manufacturing ready to go into high gear to put it out there when it's ready.

ever notice how easy it is to identify the CNN parrot points.... but how hard it is to find one that says anything positive about Biden or Harris?

LOL. Nixon gave a similar speech in 1968, only then it made sense: he was not the incumbent.
