Let's see if I can get this straight -
1) Willie Rennie reminds us that the Liberal Democrats have been passionate Home Rulers for 100 years.
2) The Liberal Democrats are now in power at Westminster for the first time in 65 years, and in all probability for the last time for another few decades, given that electoral reform was defeated last year. Presumably, therefore, this is the golden moment for a passionate Home Rule party to actually do something about their passion.
3) It is universally accepted that an independence referendum is on the way, giving a passionate Home Rule party a unique opportunity to use the London establishment's fear of a Yes vote to secure some long-dreamt-of concessions.
4) Willie Rennie tells us that the Liberal Democrats will in fact wait until the bargaining chip of the referendum is gone, and until they no longer have any influence at Westminster, and only then "work with the SNP" to increase the powers of the Scottish Parliament.
Great plan, guys. Someone who wasn't in the know would almost be forgiven for thinking that this whole "passionate Home Ruler" business was a bit of an affectation.
