Labour's Jeremy Corbyn took his party way to the left, leaving the more moderate ground where many voters feel most comfortable, including some in his own party and outside. He promised revolutionary change, a fundamental overhaul of society, heavy new taxes on the rich and a far bigger role for the state in the economy. Sound familiar?
Debate has rocked the Democratic Party over whether candidates like Bernie Sanders and Elizabeth Warren are trekking too far to the left and leaving moderates behind. Both are promising an assault on billionaires and a state-run health caresystem -- a huge chunk of the US economy. Both also dismiss the idea that their political purity is a vote killer.
