I think the lines are blurred, sure. However there are plenty of politicians that really just kind of do their job and stay out of the limelight, whereas celebrities are by default in the public eye. Also, the biggest difference is the part where you vote for a politician and they set policy. I don’t vote for celebs, and I don’t call them telling me what to wear or watch “policy”. We’ve had 2 legit celebrity presidents and they’ve both been disastrous.
