5 years is no time to put right 13 years of damage on the scale of what's was done under New Labour - gold sales, PFI, mass immigration, illegal wars to name a few. The fact that we have a coalition govt. hasn't helped matters because one side or the other has tended to block things which otherwise would have been done purely out of short term self interest and point scoring. I'm not saying any of these people are perfect or even worthy of a vote but it's clear which govt. has the most legitimate excuses. Right now things are improving unlike pretty much anywhere in Europe. If anyone thinks that would be the case had Brown won last time out they're Arthur.
Things could certainly be better and mistakes have been made but I think it's unrealistic to expect any govt. to have all the answers which I why I've stated more than once that I'll be voting for the least worst option.
