Not really sure why this has to be a PST increase, or (as suggested by someone else, property taxes).
Because Christy doesn't want to take the fall for raising taxes and instead can point to "the people" wanting/not wanting to fund transit. The Libs don't really want to impose any kind of tax increase, hence the Leadership Fail.
You make it sound as though the un-poor don't pay, but they do and will pay the most which is just as it costs more to subsidize the infrastructure for their cars. But you knew that amiright?
So why does the Provincial government just go ahead and fund vehicle infrastructure out fuel taxes and general revenue instead of holding a referendum? If the Government is serious about reducing gridlock and improving transit, why don't they make it a priority pronto instead of holding a referendum?
