Hmm yeah they are diffetent, it's a reasonable enough fit for this comparison.
Chalk and cheese - nah more like chedda and Edam - whilst you can point out the obvious, that one is orange and has a wax layer it doesn't negate the fact that leaving one unwrapped and outside the fridge will have a noticeable effect as the impact of that action is significant enough.
There are many differences such as the kind of party and economics. While UK Labour might be regarded as 'left wing' the actual running of the country was moderate conservative under them. Similarly a French government deciding to splurge money and hope for the best can't be compared to a British one being far more prudent in it's spending.
Remember also that it was THE BANKS who got us into the mess in the first case - not the political parties. Much of the money that ended up being owed by the government was because they bailed out the banks, not because the government spending was excessive.
Labour warned the coalition they were making a huge gamble, the political pundits warned they were taking a huge gamble, and guess what? They took the huge gamble and got snake eyes.
George Osborne comes from a family of gamblers. So far it has paid off for them personally. It looks like it didn't for anyone else though.
