What I don't understand is what the hell party politics has to do with providing park benches and emptying the bins?
at the risk of a (semi-)serious answer..... "the right" tends to think there should be less public provision, and people should pay for their own things, or clubs together if they want stuff - so there'd be fewer park benches or parks for that matter - but they might allow private estates to have their own park, from which the poor can be excluded, and maybe a fee charged for entry. "the left" on the other hand will confiscate money from us all, in order to waste it on things like disabled lesbian theatre groups, and other pet causes. Thus, even park benches might be party political. And bin emptying - should it be a public provision, paid for out of the rates, or should each householder contract with his own bin emptying company? After all, the public provision of bin emptying is only an excuse to create jobs for workshy trade union lefty types who couldn't survive in the private sector...
Well, maybe not serious, I got carried away...
Slightly more seriously, there's basic common services with even the right (at least the moderate right) thinks should be common, then the Party aspect is who makes a decent job of running it, then as each side mucks up and / or gets complacent or their noses in the trough, we kick 'em out and let the other lot have a shot at it.
