JC - you are making my point for me.  We are centrists - some vote slightly left, some slightly right. We have something of a balance. 
That's because no party is very extreme or has a platform of, for example,  gutting health-care  or paying 99% tax on the rich.
Bernier may talk about a platform of abandoning fed payments for health care but his party wouldn't touch that with a  barge pole in an election.
