To put it in perspective, consider William Hague. I expect we've all seen that speech where he addressed the Conservative party conference at 16 years old.
Regardless of whether you agreed with his politics (I don't!), he was evidently passionate about politics, and confident. Checking wikipedia, he became the Conservative Party's then-youngest MP after being assigned a safe seat at the age of approximately 29. Then it was a meteoric rise to becoming conservative party leader at 36.
He obviously always aspired to be an MP, but he was obliged to go to university and do student politics first, wasn't he? The eighties were a different time, but I don't think the Tories today would tell a modern day teenage William Hague that he could go straight into politics with them.
