The Kamala Medicare for all plan would destroy our Senior Citizens Medicare Program!
No one on this end said Medicare for all is part of the Biden platform 
What has been pointed out is, the likely hood that Biden, if elected, will not fulfil his full term because of health issues, and Kamala will step in as president, and she has supported and promoted the destructive Medicare for all plan.
Finally, you are flat wrong is asserting Medicare for all would not negatively effect our Senior Citizens’ Medicare program. see: ‘Medicare for All’ Would Be Terrible for Seniors
October 26, 2018
"In a rare op-ed, President Trump recently suggested that “Medicare for All” proposals gaining popularity among Democrats would “demolish” the Medicare benefits that seniors expect to rely on. This provoked Senate minority leader Chuck Schumer to issue an angry rebuttal scrawled in red pen, in which he denied that Democrats supported single-payer health care and declared suggestions that Democrats had plans to outlaw private health insurance “NOT TRUE.”
But the article continues: “Although Schumer suggested that seniors might welcome reforms that “would expand benefits, eliminate premiums, reduce cost sharing,” having taxpayers assume these expenses for all citizens would be enormously expensive. Indeed, Schumer revealingly didn’t dispute the estimated tax increase of $32.6 trillion over ten years (over $26,000 per household per year) cited in Trump’s op-ed, which would be required to fund “Medicare for All.”
The unfortunate truth is, electing Joe Biden as President, and expecting him to complete his full term in office is a crap shoot which more likely than not, will end in a Kamala Harris Presidency and the adoption of her destructive “Medicare for All” plan. And that plan would surely destroy our Senior Citizens’ Medicare program which they have paid into all their lives.
At least President Trump is not a threat to our Senior Citizens’ Medicare program.

The Biden/Harris Administration’s plan to keep Obamacare, which currently covers less than 9 million people ___ many being foreigners/aliens ___ will outlaw the existing private health insurance plans for over 150 million American Citizens, and force them into a Communist/Socialist, Cuban style healthcare system.
