Permit me a dubious analogy.
My main topics so far have been politics and football, so I'd thought I'd do a bit of a mash up.
Let us consider that Chelsea and the Tories are in the blue corner, and Manchester United and Labour in the red corner.
The blues have a vast amount of financial backing form a generous benefactor, and on such a basis you'd expect them to do very well, yet this isn't always the case. Big supporters of unregulated capitalism.
The reds have been crippled by stupid financial practices and have mortgaged their futures. To fail now could see a rapid decline. Once a home to many a socialist, they've sold out their values yet remained popular. Much trouble in the ranks, with some splits in recent years, and on the verge of outright rebellion if success dries up.
[which would make FC United something like the Socialist Workers Party]
Then there's the yellows. There's not a direct team comparison here. Norwich or Watford maybe, as they play in yellow? I'll run with Spurs and keep it all Prem, lets pretend they're in their yellow away kit.
The yellows have picked up a lot of neutral supporters who want to see the hegemony at the top broken, a new challenger to the big boys. No one is expecting them to pick up the top prize anytime soon but there's a general feeling that it's a good thing that someone else is competing.
I'm about to jump the shark.
UKIP = Bolton. Have been known to sign a big hitter from one of the big boys but generally finish mid table at best, generally lower. Tactics show a lack of ambition. No one is quite sure why they're still here.
Greens = Fulham. Most people have nothing against them, they might pick up the odd success but never likely to start a title challenge.
The Nationalists (all varieties) = Celtic/Rangers. Do well in their own league but don't stand up to scrutiny on a bigger stage. Essentially bigots.
Respect = Portsmouth. Had some big name signings a while ago but it looks like their party is almost over. Those who fuelled their early charge have gone on to wider 'fame' and what momentum they had burnt out a while ago.
Monster Raving Loony Party = Newcastle. Completely mental. Crazy policies, but generally quite popular despite a lack of any success. A good side show.
Pirate Party = Burnley. Have made a brief raid into the public consciousness but were never likely to sustain any serious challenge
Veritas = Hull. Once led by a controversial bright orange chap, now directionless and on their way out.
