I Don't Recall Dion Receiving A Letter from Kennedy saying "No Cooperation with Greens".

Bravo to Elizabeth May who has knows how dangerous Harper is for this country, and instead of playing partisan games with other parties, has managed reach a deal with another party that benefits both in the long run. Of course the fifth party is up in arms, only because they want Harper in power has long as possible so they can hold power is some post-apoctolyptic Canada. The NDP claims there is no difference between Conservatives and Liberals, so who is in power doesn't matter.
Deals between the NDP and Liberals go back to the days of Douglas and Pearson, with most of them falling through. On the provincial level they are even more common. In Ontario, the McGuinty Liberals proposed not running candidates in certain ridings in an attempt to defeat Mick Harris, only to have the Hampton NDP back out at the last minute, causing the Liberals to scramble to run candidates.
Good to see two parties working together on the election front, and instead of bickering back and forth on who is more rightious and allowing a third party to sneak up the middle.
