“Biden is seen as moderate.”
Biden needs to be seen as pretty much a failure except for being a US Senator from a small state.
He is a vote buyer and is prepared to snatch corporate and personal money to get ahead.
Biden is not as left-wing as Sanders, but he will ensure leftists rule the USA for decades.
These leftists will impose wealth taxation in Sanders style.
Biden is not a safe choice for those with wealth or those willing to work.
