Tories were also all for the war on Iraq, you know. Tony Blair to me represents everything bad about Labour to this day.
They seem so stubborn to anything vaguely left wing, that they've even resorted to deliberately sabotaging Corbyn's chance of getting Labour into power at the December general election. He was never the best in terms of optics, sure, but he was trying to move Labour somewhat back to the left (even if proposed policies were socdem at best).
