Not at all. I'm not a fan of any bashing of the other side. In Palin's case, there are so many real and valid criticisms of her candidacy that you're harming your own case against her when you resort to this low garbage. Maher has always struck me as a misogynist pig at his core.
Palin was both unqualified to be the VP, in terms of education and experience. She was the Mayor of Wasilla, population approx. 9000 people, before being elected Governor. She then ran for VP a little more than a year after becoming governor. She doesn't appear to have even graduated college or university, although she made several tries over the years. I can't even imagine her as President, which is a very valid consideration given McCain's age. She's done absolutely nothing since leaving office to change my opinion of her.
When Andrew Scheer was debating Justin Trudeau during an election campaign, the question asked was "As Prime Minister, what changes would you make to Canada's current foreign policy?". With 2 minutes to reply, Scheer launched into an attack along the lines of Justin Trudeau is unqualified, and he did this that and the other thing. The moderator said "Mr. Scheer: The question was what would your foreign policy be if your were Prime Minister". He followed up with more attacks on Trudeau.
Elections are supposed to be about good governance. How do we know if you can do the job, if you spend all of your time, telling us what a creep your opponent is? Tell us why we should give YOU our vote.
