Swinney is catastrophically bald and has a ministerial track record to boot. He's better than Humza but it shows the real dearth of political talent up here. A safe pair of hands until some of the SNP talent from Westminster can be redeployed following the GE.
As for the scaremongering about minority government. The SNP governed just fine from 2007 to 2011 as a very small minority government. It means compromise and working with the other parties. That isn't something to be feart of it may well improve things.
