In lieu of an analysis of my own (see below for excuse), I would like to point you to a summary of the week’s developments made by my colleague Flemming Juul Christiansen and posted on the PSA Scandinavian Politics list.
If you understand (spoken) Danish, I would also recommend last Friday’s edition of “Ugen på spidsen” where Claus Hagen Petersen interviewed Anders Samuelsen, MEP (formerly of the Social Liberal Party, now one of the leaders of New Alliance) and Anders Kloppenborg, who used to be the party secretary of the Social Liberal Party.
Short summary: Tax policy as a central issue, the Social Liberals’ problem with lack of parliamentary influence, the problem with a lot of new left-leaning members in the SLP and the prospects of a major realignment in Danish electoral and parliamentary politics.
Also worth noting was the lack of venom against old allies from Samuelsen and Kloppenborg. Some might say that this is typical of the Social Liberal style of public argument.
