I looked up this mayor too. I can't find much criticism of the federal admins policies. What I do find is that she is an active supporter of Israel, she voted to invade Iraq, and she has been named as one of the US' most corrupt representatives.
So, maybe you can reflect a bit on why people aren't very ecstatic that a politician is a Democrat. As far as I'm concerned, she has aligned herself with the leopard-eating party by begging Canadians to be complicit instead of pushing back against the federal admin.
