A great article and all valid comments that resonate with me. In the past I've been a proponent of the wasted vote theory (although until recently I lived in a LibDem constituency - so I could vote LibDem and win!) but now I realise that in a Democracy no vote in a wasted vote and it's more important to vote for who you want to win rather than to engage in Tactical Voting. Only by voting correctly do we show the true sense of the failure of the two party system.
So this time even though I know that the Conservatives might just beat Labour in my constituency I am going to vote on who I think should win, the Lib Dems.
One more point. I often get the feeling that the local parties let the national party down as I keep seeing multiple comments complaining about the poor quality of local councillors. It worries me about them on a national level
