The conservatives are still ahead.
And now for some free and unsolicited opinion and advice:
I have empirical proof that statistically there is a higher incidence of inmates who vote for the Liberal Party than for the conservatives. That does not mean that Liberals are criminals but it does mean that criminals are more statistically likely to end up in that party than other places.
For those satirically challenged: President of EKOS Frank Graves:
“I do believe, and this gets more subtle, that there is a higher incidence of people who are less tolerant to homosexuals and more wary of other races, within the Conservative Party. I can demonstrate that empirically."“That does not mean that Conservatives or Albertans are homophobic or xenophobic, but it does mean that many people, and more people statistically that have those points of view, end up in that party than in other places."
