The Lib Dems are loons. Their policies are a mix of the interesting and the bloody silly. In the ordinary course of politics, sometimes the main parties nick their best ideas. I would not be thrilled to experience their worst ones. And Nick Clegg... well, to me he seems like a blank space on to which the electorate are projecting their hopes. Mr Not The Other Two.
But the Lib Dems are loons *because* of the two party system. If you want to go into government, you have to join the Tories or Labour. The Lib Dems get the leftovers. If they had more chance of getting into office, they would attract more talented politicians. Electoral reform would let that happen. And liberal ideas -- the deep underlying ones, not the wacko policy proposals -- are pretty decent ones. Liberalism is more alive as a set of ideas than anything Labour has got.
So, do you vote for the loons now, in the hope of getting something better later?
