All I know is a while back on the Big Hollywood site, it was reported that he appeared on some tv show which had some sort of anti-conservative message and he basically said he didn’t care about American politics because he was Canadian. That’s all I need to know.
BTW, I know some very wonderful Canadians who DO care about American politics.
I, actually, read somewhere that Justin Bieber is pro-life and a conservative (from Conservapedia). He, often, visits hospitals and charity groups, too!
