So ... PMSH has once again prorogued parliament - only a little over a year after the last time he pushed that button.
Normally, the governing party prorogues parliament when it has accomplished the bulk of what it set out to do in the last throne speech. At that point in time, the government needs to adjust its direction and a prorogation is quite appropriate.
That is not what is happening with Harper. He's using prorogation not just as a political tool, but in fact he is using it in a way that guarantees that his government will never actually pass any substantive part of its legislative agenda.
In short, the Conservatives are legislatively bankrupt. They keep clobbering their own legislation mid-stride, and have to reintroduce it. I'm sure it makes for good propaganda - after all, they can continue to spout off their nonsense about being "tough on crime" and so forth without actually having to deal with the consequences of truly brain damaged legislation.
The fact is that not only is Harper scheduling himself an extended vacation at taxpayer's expense, but his party is out of ideas. They have no real legislative vision - they'd rather govern from behind closed doors as much as possible.
