"They...have pussy footed around banking reforms and have done nothing to really crack down on top tier tax dodgers."
Neither did Labour; Mandleson 'supremely relaxed' about rich people (they did nothing about cracking down either - in fact permitted the offshore exemption for stamp duty). Labour did nothing on banking reform after the crash, although they said they would, nothing.
However, Labour were better on social matters such as civil partnerships, etc. and they scrapped s28 (legislation against 'promoting homosexuality') put forward by the Conservatives. So, David Cameron saying 'I support gay marriage because I'm a Conservative' sounds a little odd this side of the pond, too.
