The SNP did not 'help to deliver a Tory Government'.
We have a Tory government because people in England voted for one overwhelmingly, and they have a massive in-built majority in the Commons.
This result illustrates starkly that the politics Scotland votes for will always have precisely fuck all influence on the Government at Westminster.
The need for electoral and constitutional reform is now overwhelming but I fear that, with the Tory majority any that does take place will be on their terms, so we can expect fuck all.
