The Conservative support has dropped since the election and the NDP keeps on rising. The 2 parties are now tied with 33% support each. Liberals are in 3rd place with 21%.
Pollster Allan Gregg attributes the rise in the NDP support to the effect of Jack Layton's passing. But the NDP was slowly rising already before their leader passed away. And this doesn't explain the big drop (7%) in Conservative support (or does it?).
I've read about many people who didn't vote last time say that they will vote NDP next time. So, maybe we are looking at added decided voters supporting the NDP.
