"It would not have been appropriate for the government to intervene. This was a local government affair."
Well yes but.
The inexplicable (or at least so far unexplained) bit is why Transport Scotland was involved in (presumably) signing a contract that notionally said 'payment for progress' but turned into 'payment for invoice'.
"Swinnney was able to step in after the Haymarket vote because there was a material change."
Well yes but.
It's hard to say that that was the first "material change". It had previously been voted on by CEC to only go as far as St. Andrew Square. Also, for a long time, it's been clear to most people (not including the councillors on the tie board of course) that there was not enough money to get anywhere near Newhaven.
Now 'we' - as Edinburgh Council Tax payers are being asked to cover the cost of borrowing MILLIONS more for something that is clearly no longer 'value for money' - even if it was when all Scottish taxpayers were chipping in.
"perhaps he is a nicer person than me". Hard to say - haven't seen you on Newsnight...
I believe he could have done more and sooner. But there were certainly legal constraints as well as political considerations.
Overall he probably made fewer bad decisions than most of the other people involved, but as a finance minister, probably more prudent than the Westminster one from Fife, I think he should have wanted (AND MADE SURE HE WAS ABLE) to keep a closer eye on the £500m.
The fact that he hasn't (been able to), means he is not popular with some voters along the A9.
Lothian Buses could do quite a lot with a share of £500m.
Or it could buy 1000 Quality Bike Corridors.
