I have qualms about casting Harris as a "career" politician. He first election for DA was in 2003. To get from running for DA to running for US President in 21 years is a very short ride. She was born in 1964.
Hell, Trump ran for President (Reform Party) in 2000, so he's been a "politician" longer than Harris. So if she's a "career politician," then so is he.
Not that there's anything wrong with being a politician for a long time, as long as the politician is serving her constituents to their satisfaction and avoids corruption.
