Everyone seems to forget that the political landscape can change quickly, and its another 4-5 years until the next election. Labour are probably happy to make the unpopular decisions now, in the belief that there is plenty of time for them to make amends - and if those unpopular decisions have positive results in the longer term, all the better.
The country is a mess. Im not going to pretend Labour have particularly impressed me so far, but equally they dont really need to. They need to arrest the decay and get some positive change in motion for the next several years. They will be judged at the next election, not a few months into their tenure. Anyone expecting miracles and rainbows after 3 months is living in a dreamworld.
