I'm not a fan of two party politics never mind one party like we effectively have in Scotland, but with an opposition as weak as any of them what we have is porobably ok. Biggest problem is that there are no politicians in Scotland worth the money we waste on them bar a few.
But... it's not the SNP's problem that nobody else is capable, Labour couod have done something clever when Johanna lamont quit instead Millibland put his puppet and Admiral Ackbar lookalike Jim Murphy in place, he couldn't argue his way out of a fight at playgroup and who is Willie Rennie the Lib dem guy, never heard of him.
We can discuss and debate but only the 7th will tell, i suspect it'll be a very poor night for anyone other than the SNP in Scotland.
