Haha, what a pointed reply. This is just my opinion, but I'm gonna try and refute your claims:
1) Provincial nominations won't all kick in at the same time, and it's not a guarantee, for example, that all 2,700 Ontario PN applicants will be approved and selected. I am sure that there are quite a number of rejected applications. So, even if next month we see there's 1K applicants with PN in the pool (Which is extremely unlikely btw), the regular number of ITAs in a draw, which is 1500 lately, would likely absorb all applicants with the PN and then a few stragglers, bringing the score down to it's current average of 450~. We are not gonna see CRS score rise and stay in 700s just because of PNs.
2) The reason the score will fall bellow 450: As CIC has said it numerous times, there's currently a backlog of old applications that are still being processed, but once the backlog is eliminated, EE will be the main source for selecting immigration applicants. Less backlog = More ITAs sent out = Applicants with scores bellow 450 get selected. The backlog for FSW applications is set to be gone by 2016, and I know for a fact that as late as December 20, 2015, the backlog for CEC applicants will be completely gone. So next year, which is only 3.5 months away, will bring a completely different EE selection process.
3) When it comes to the elections, this is were you are the most wrong. Each of the political parties running has a clear stance on immigration. One great example is Lysane Blanchette-Lamothe, the critic for Citizenship and Immigration in Tom Mulclair's team. She has been vocal and critical about Express Entry since the beginning, blasting Chris Alexander any chance she gets in Parliament. If the NDP wins, she's the new MP for Citizenship and Immigration, taking control over Express Entry. On the other hand, if the liberal party wins, they have promised to introduce an in Canada fast-track program to allow temporary workers, international students, and live-in caregivers to apply for permanent residence within Canada faster. Both the NDP and Liberal parties are currently ahead of the conservative party by at least 3 points in the polls, and the elections are 5 weeks away. The elections will have LOTS to do with immigration.
