The SNP party has imploded but the reason for voting for them has not gone away. Which is why I believe that their share of the vote will not diminish as much as some people think. Yes they will lose some MPs and councillors, but they will still be the biggest party in Scotland, and send more Scottish MPs to Westminster than the other parties.
Local Elections before a General Election do tell us something. They tell us how unpopular the party in Government is. The party in Government usually do badly toward the end of their term, the question is, how badly? So yes, the Conservatives can lose these Local Elections, and still go on to win the General Election if they don’t lose too badly on Thursday.
