26. Then you haven't been paying attention. Joe Biden ran on some version of most of these policies in 2020

From Politifact's 2020 Biden Promise Tracker (If he promised it then he definitely explicitly ran on it)

https://www.politifact.com/truth-o-meter/promises/biden-promise-tracker/

Introduce a constitutional amendment to eliminate private dollars from federal elections

"Introduce a constitutional amendment to entirely eliminate private dollars from our federal elections. Biden believes it is long past time to end the influence of private dollars in our federal elections. As president, Biden will fight for a constitutional amendment that will require candidates for federal office to solely fund their campaigns with public dollars, and prevent outside spending from distorting the election process. This amendment will do far more than just overturn Citizens United: it will return our democracy to the people and away from the corporate interests that seek to distort it."

Work to codify Roe v. Wade (Remember this was before it was overturned)

"As president, Biden will work to codify Roe v. Wade, and his Justice Department will do everything in its power to stop the rash of state laws that so blatantly violate the constitutional right to an abortion, such as so-called TRAP laws, parental notification requirements, mandatory waiting periods, and ultrasound requirements."

Offer a public option health insurance plan like Medicare

"Whether you’re covered through your employer, buying your insurance on your own, or going without coverage altogether, Biden will give you the choice to purchase a public health insurance option like Medicare."

Increase the federal minimum wage to $15/hour

"Increase the federal minimum wage to $15 across the country and eliminate the minimum tipped wage."

Create a bipartisan commission to consider reforms to the Supreme Court

"If elected, what I will do is I'll put together a bipartisan commission of scholars, constitutional scholars, Democrats, Republicans, liberal, conservative. And I will ask them to ... come back to me with recommendations as to how to reform the court system because it's getting out of whack, the way in which it's being handled. And it's not about court packing."

No tax increase for anyone making less than $400,000 (Implicit in this was he would raise taxes on hire earnings since Republicans were accusing him of wanting to raise everyone's taxes)

"Under my plan, if you make less than $400,000, you won’t pay a single penny, more in taxes. You have my word on it."

That original list didn't include many other things he explicitly ran on:
-Restore ACA's contraception mandate
-Eliminate the federal death penalty
-Expand and increase Social Security benefits
-Protect military personnel and veterans from deportation
-End the online sale of firearms and ammunition
-Add 150,000 community health workers
-Create a pathway to citizenship for nearly 11 million people
-Expand broadband, or wireless broadband via 5G, to every American
-Rebuild health stockpiles to be ready for crises
-Forgive student loan debt from public colleges and universities
-Lower cost of prescription drugs
-Decriminalize marijuana
-Update the Voting Rights Act
-Offer universal preschool to 3- and 4-year-olds
-Prevent the White House from interfering in federal investigations and prosecutions
-Offer up to $8,000 tax credit for child care
-Put Social Security on a path to long-run solvency
-Raise corporate tax rate to 28%
-Reauthorize the Violence Against Women Act
-Rejoin the Paris climate agreement
-Reverse the transgender military ban
-Rejoin the World Health Organization (WHO)
-Immediately rescind the “Muslim bans”

There's tons more as well. Biden ran on every one of these specific issues. He accomplished many of them but not all due to inaction of Congress.

You're parroting right wing talking points saying Democrats are never specific. This proves Biden was very specific on a multitude of policies, you just weren't paying attention. Go back and Watch Kamala Harris's speeches from last year - she repeated most of these "promises" that Biden wasn't able to accomplish in almost every speech she gave.
