We look at Biden's long record of success. For example, This is major stuff. You would be hard pressed to name any politician with a more impressive record than Biden.
I am slack-jawed in disbelief that you would even offer that! Joe Biden, the guy that when Obama picked him, I asked: "Who is that?" If you think Biden's record is among the best in Washington, that is a slap in the face to all taxpayers. This for a man a HALF CENTURY in government:
1. Biden is responsible for the Violence Against Women Act.
Seriously? Is that a campaign issue in 2020? Where is there violence against women in the news?
2. Biden introduced the first climate bill.
When? How many times has it been proven wrong and a myth since? Hopefully Trump killed it.
3. Biden was for civil rights even before that was cool.
Judging by this summer, doesn't look like he actually DID anything for it though.
4. Biden has stood up to the NRA.
You mean the organization which works for gun safety, police training and self-defense?
5. Biden put the kibosh on the fascist Bork.
Bork? How many decades ago was that? Three? Think you can find anyone on the street these days who cares about Bork?
6. Biden has always backed veterans -- for real.
Must be why he left Vets to rot in the VA hospitals, depleted the military and all Vets are for Trump.
7. Biden has always worked for campaign finance reform.
I guess that's why it is still unchanged with him among the most corrupt in DC.
8. When the Bush admin didn't want MRAP vehicles in Iraq to protect the troops, Biden pushed them through.
Another really hot-button topic from 20 years ago.
9. Biden was a voice of reason around 9/11.
20 years ago again. Has Joe done anything since?
10. Biden pulled together the votes for many of Obama's accomplishments.
Great. Joe helped fuel what many consider the worst and most corrupt admin. in history!
11. Biden was an early supporter of gay marriage.
There's a biggie. Supporter for pedophilia, too?
12. Biden ran the awesome Obama economic recovery.
Awesome? You mean the slowest recovery since the Great Depression! Pretty easy to replace jobs when you don't have any to begin with, especially with shovel-ready min. wage ones. Come to think of it, I don't remember ONE TIME Obama ever said: "Don't thank me, Joe did it all!" Never mind the fact that Joe and Obumma were among those in the Senate that helped CAUSE the economic collapse in the first place! 
Sadly, you can't even offer a SINGLE THING there that is even an issue relevant in the minds of voters today in why a nation should replace a president, especially in the middle of a serious health and economic crisis fraught upon us by a foreign enemy (which Joe is buddies with).
VOTE FOR ME, JOE BIDEN, I OPPOSED ROBERT BORK THIRTY YEARS AGO! 
Mary Ellen Bork, widow to the late Judge Robert Bork, wrote an article reminding readers of Joe Biden's role in her husband's failed confirmation.
