Beyond the above, I think the strong Liberal team should be sold to the public. There is a huge amount of skill and competence to contrast with the Tory cabinet joke.
To that end, Rae will get slagged by opponents for his rocky Premiership in Ontario. To counter that, the Liberals should be promoting Rae's international experience of mediating in Sri Lanka.
I have a great deal of respect for Lloyd Axworthy, who spearheaded the anti-landmine campaign and deservedly received a nod for the Nobel Prize-winning work. Rae and others can further this popular legacy of peace and mediation; I think Ignatieff's missteps don't poise him to stand on his own at this point.
