One of the many things that Starmer has pissed me off about was him going on about one in seven Scots are on a waiting list and that this was an indictment of the SNP Government in Holyrood. 
Given that Scotland is dependent on its pocket money budget allocation from Westminster and that one in seven are on waiting lists in England, then I'm not sure what point he is making 
However, people only hear the sound bites and the expressed criticism and don't check the background facts for themselves 
I'm not saying that the NHS is perfect up here - but by most measures, it is doing a damn sight better than the NHS in England.
For example: ds' girlfriend was in an out within an hour on Wednesday at A&E, rang for a GP appointment the following morning and was seen in person by the GP at 11.20 (although the "priority" ultrasound which probably won't even identify the issue which needs an MRI
has a waiting list of 3 months
), dh and I were both seen by a new NHS dentist in the last couple of months (which reminds me: ds and his girlfriend need to register with them as dentistry is free for them until they turn 26), pharmacies can dispense basic antibiotics and other medications free of charge which in turn takes the pressure off GPs....
Having let go off that rant
, if I lived in England, I'd be voting tactically to get out the Tory if I lived in a currently Conservative constituency.
