I sometimes get depressed at the state of politics in this country. Often.
However, the prospects opening up are ...interesting.
Possible results:
Labour led hung parliament = massive wrangling with Lib Dems, discrediting of both, (allowing possible advances for left/greens at subsequent election, made easier if Lib Dems actually do the only thing they are useful for - gain PR).
Tory led hung parliament = massive wrangling with Lib Dems, possible unrest if Tories get their way, weakening of some of their worst attempts, possible massive dissillusionment in rightist ranks if Cameron is "liberal" in practice rather than just rhetoric and possible early further election with chance for Left/Greens to regroup.
Tory Government = Probably on minority vote that all are now aware of - potential for massive opposition and unrest and demands for electoral and political reform.
All options entail major problems for the establishment and the ruling class and opportunities for radicals - never a bad thing.
