Yup, a lot of folks get too hung up on who the figurehead is when ultimately he's one guy. A guy in a significant position, but still one guy. Every prime minister has their cabinet and an entire government machine full of staff behind them. Party policy, history, party platforms, these are much more significant than an individual figurehead, and they're what folks should be looking at when considering who to vote for.
This isn't to say the figureheads don't matter, of course they matter, we should be paying attention to what they are and aren't saying, what they're broadcasting, but a lot of folks seem to give them more influence in their minds than they actually have.
Lot of folks won't vote liberal because of Trudeau, I wish the Libs would run someone else to counteract that. A lot of folks will vote against their best interests because they don't like the puppet, as you've said.
The Cons aren't interested in the average Canadian, they're interested in factions with money, and those with wealth. The Libs will never be perfect but at least they probably won't slash Canada's social safety net the way the Cons like to.
