A hiding to nothing?

The Independent thinks that an early general election will favour the SNP:

Nicola Sturgeon must be rubbing her hands with glee at this moment.

In the aftermath of Theresa May’s announcement to hold a snap election, Sturgeon knows how most Scots will receive the news: badly.

Provided May is allowed to hold the election by Parliament, it will most likely lead to a Conservative victory and further degradation of the opposition – one poll predicts the Conservatives will end up with a 100-seat lead in Parliament. So long 2020: May could stay in power until 2022.

Sturgeon’s tweet after the news hit the nail on the head: “The Tories see a chance to move the UK to the right, force through a hard Brexit and impose deeper cuts. Let's stand up for Scotland. #GE17,” she said.

Me, I'm not so sure.  The SNP already holds 56 of the 59 Scottish seats.  The best that Sturgeon can hope for is three gains and no losses, a relatively modest return which would do little to increase the SNP's influence at Westminster.  On the other hand, even one or two losses would be portrayed by unionists as a roll-back of the SNP tide.  And would an increased overall majority for the Tories increase the prospects of an IndyRef2 in the short to medium term?
