It's a good strategy to cause a rift in the right. PP is trying really hard to gain the GTA, which is full of indians, so he panders to them really hard. CPC voters everywhere else want less indians and are really fed up with them. Heck, even the cbc and the MSN overall are starting to run negative indian news, something they would have never do to such an extent just last year.
And considering that PP went to dilahwi events during Thanksgiving, the rift is there to be exploited.
