And they get away with it because again ... the population falls into thirds
A third supports this stupidity, a third oppose this stupidity and a third are completely ignorant and don't care who wins the argument.
Movements like this come out of small group of small minded people with a lot of funding and monetary support. They just don't appear out of thin air. Their rhetoric grows because they are able to market it to many people in many places, often and effectively. It takes money to do that, not influence, not charisma, not luck ... it's just money.
The NDP has leagues of diehard supporters, but none of them ever get heard because they don't have a marketing machine behind them. I know because I'm an NDP supporter.
The marketing is only half the problem ... the other half is the ignorance of the masses. Conservatives know that they can sway a good percentage of the population ... they also know that with careful marketing, they can sway those that sit on the fence or are just ignorant of everything. It's all they need to nudge themselves into power.
Everyone needs to vote, everyone needs to make their voice heard ... it's the only way we can stem the tide of conservatism that is building.
