The grandparent is a good example I think sarcasm should be verboten on any serious discussion forum. It's impossible to argue with because it shields the wielder from having to make an actual clearly stated argument.
Problems with great grandparent:
-Campaign finance is heavily regulated in the UK and about half of it comes from the state.
-UK media is less of a political frenzy. They have other things to talk about, like the premier league, or human affairs.
-The closest thing to US liberals language-wise are the Liberal Democrats, who are part of government. The closest thing to US liberals politically are the Conservatives (e.g., combating climate change is high on the conservative agenda)
-Liberals aren't gaining any seats in polls
That's a few too many errors for sarcasm to work.
This is true, in that there are limits both locally and nationality to how much candidates can spend on election campaigns.
> and about half of it comes from the state
AIUI this is not true; political parties have to raise their own money not get it from the state. There is funding of political parties, (see Short Money http://en.wikipedia.org/wiki/Short_Money ), but it isn't for the running of campaigns.
