What makes Newsome appealing as a presidential candidate is that he is from CA, an unabashedly leftish state. Just as Trump is willing to impose his personal views on America and let the courts figure it out, Newsome is willing to impose leftish views on America. After Trump, the country will need to make a sharp left turn, UNDO EVERYTHING that Trump has done, claw back every dime that Trump and his acolytes have stolen, give all Trump appointees the boot, hire back as many employees that Trump has gotten rid of that want to return, rebuild/re-establish all agencies, tear out all of the "renovations" that Trump has made to the WH and its campus, etc., etc., etc. And, last but not least, fumigate the f'n place.
lower rates would cause them to lend less to riskier borrowers with patchier credit
IOW: Charge everyone the same rate irrespective of their credit history and in this way, people with better credit support those that don't.
If banks really wanted to demonstrate the truth of that statement, they would peg their interest rates to the credit worthiness of the card holder!
