Consistent with why I'm not keen on Biden. Or, for that matter, on the Lib Dems or most of Labour's alternatives to Corbyn. Business-as-usual got us here, I'm not sure why one would expect it to turn out any differently if we tried it again.
I suppose someone who is bold in a boring way would be best. Seems like both Corbyn and Sanders have some 'baggage' that gives them vulnerabilities (possibly Corbyn most of all), but there isn't a lot else on offer. It's possible Warren would be better (she just seems to lack that populist motivational capacity that seems to be necessary these days)
Here, I haven't a clue, Blair seems to have left behind a complete vaccuum in Labour, everyone apart from the old left seems to just be an empty space, still wondering where all those ministerial salaries and expense-accounts went.
