Obama ran "left" (populist left of center) in 2008.
he won.

because he organized his ass off and was a better salesman than the rest.

and the media tolerated all kinds of lies and bullshit about him because it wasn't supposed to be his "turn".

the only thing someone running "too far left" has to fear is not getting out the vote and not having the right responses to the media bullshit.

it basically was Bill Clinton 2.0. (so was his presidency, sans impeachment)

Hillary lost because she came with baggage, treated the GOTV effort lackadaisically, and underestimated the ability of the right wing to congeal around a joke candidate like Trump.

this is the wrong take from the UK situation.

their voting wasn't necessarily for Boris. it was in response to what people thought was a betrayal of democracy, that the Tories easily exploited. it also was buttressed by a whole lot of lies from the media. this took the "Crooked Hillary" nonsense to an even lower point.

it was the Bidens and Buttigiegs in the UK that turned Labour the wrong way, not the "far left" politics
