I'm not sure the answer is obvious. Party politics the way it's practised in most western democracies can certainly look flawed. Politicians are generally perceived to be dishonest and opportunistic; the public are so turned off by the whole charade that they turn out in pathetically small numbers, except where voting is obligatory; there's sometimes a sense that corporate interests, rather than the electorate's interests, are being served, especially in the US where big money is allowed to play a huge part in the process.
Politics is bad, mmkay.
The usual riposte to this is that democracy may be flawed, but it's the least bad system anyone's found, and I think there's some truth in that. I also think that most politicians don't deserve the bad reputations they have. I live in the UK, and have met a number of reasonably senior politicians, and while I haven't always been impressed by their intellectual calibre, knowledge of specific areas, or even basic articulacy, I have at least been persuaded that they were honest, sincere and well-meaning. Clearly that hasn't always been true of all, but my strong impression is that the bad apples have been isolated exceptions. They are also highly accessible to their public. The electoral system here is crude and can produce anomalous results, but at least when the public is thoroughly fed up with the government, it is very able to throw them out of office, as it did with some relish, for example, in 1997 (Tories out, Blair in).
Politics is good, mmkay.
I'll cast my vote for the latter half of my post.
