I think he's disappointed. I think many on the left and right are finding out that their political parties no longer have anything to do with ideologies they believe in.

For a long time the UK has had Labour (liberalish) and Conservative parties. Labour was classical liberal (free market, small government) with traditional union ideas expanded to the nation born out of the industrial revolution: you want a strong labour force, don't maim them as children. You want a strong army, don't malnourish them as children, etc. The conservative party was the one keeping the socialist programs in check and that well and truly broke down during their current tenure. They're CINOs, and I think he's just learnt that.
