Go for it, Garth
I guess at this point every political junkie is aware that ousted Tory Garth Turner has been extended an offer to join the Green Party, and that Turner is seriously considering the offer.
I can't see a disadvantage from Turner's perspective to becoming Canada's first Green MP. It would improve his public profile a great deal, give him a party to run under in the next election, and position him as an obvious choice for the next leader of the party, which would be especially beneficial if, as a result of his actions, the Greens become a new political force in Canada. All it takes is a single MP in the House of Commons to entitle a party to participate in leaders' debates, so it's not surprise Elizabeth May is desperately seeking Turner.
