What has happened to put Ujjal Dosanjh on the outs with the federal Liberals?

Over at the Globe, Rod Mickleburgh asks the question: "What has happened to put Ujjal Dosanjh on the outs with the federal Liberals?"

From this corner, a modest suggestion for an answer can be distilled from this video from election night:



Dosanjh's strident "I'm not supporting this government on any issue whatsoever" outburst was born of the frustration all Liberal candidates felt having to explain for 36 days in the election why they kept Harper in power through 43 confidence votes under Dion. (Incidentally, that they were being “reasonable and constructive” while Harper was politicising immigration and cutting culture funding is the best they came up with).

Never a believer in cooperating with the New Democrats in a stable coalition government, Ignatieff has known for some time that he would have to resume Mr Dion’s posture.

Under those circumstances, it would be politically untenable for Ignatieff to promote a man who serves as an embodied reminder that far from being a progressive opposition, the Liberals have sunk back into the role of playing a hapless Robin to Stephen Harper’s Batman.
