Let's be realistic...

...political parties need money to do their thing.  And for the most part, people are not willing to shell out money unless they get something in return.  So provided there is no evidence of policies being specifically altered as a result of donations I cannot see anything inherently wrong in donors being rewarded by the perceived kudos of having dinner with the Prime Minister or whatever.  It's not as though this hasn't always gone on - Labour governments have traditionally cosied up to the unions and Tory ones to big business.  Such is life.  All a bit of a storm in a teacup as I see it - and the alternative of course is public funding, and who wants that?
