Help! Son is refusing to vote

[Onenightonlyplease]

Quick - I need persuasive arguments to get my 19yr old son to vote. He's on his way home and when I reminded him he needed to vote when he got back he's point blank refusing.
I don't want to get into an argument over text with him and he is beyond stubborn so I need help to persuade/force him to vote tonight when he gets home!!!

Change the wi-fi password. Tell him you'll change it back / tell him what it is once he's voted!

My DC19 hasn't voted because in his words there is no party worth voting for. DC18 has voted Labour (easily impressed, but we still love him!!).

Turn the wifi off or pinch his xbox controller and tell him he's not getting it back till he gets his arse down the polling station. Other than that there's probably not a lot you can do.

I don't see anything wrong with it unless you try to tell him who to vote for. Tell him once he gets to the polling station he can vote for the candidate of his choice, spoil his ballot or simply turn around and come home again, but as long as he's going to whine at you about politics then he can bloody well get down there.

I took a similar tack with my 21yo daughter who has hence voted for the first time ever in this election (am really happy about that cos she's asd and has a bit of a problem coming to terms with being an adult now). She has strong political views but told me she couldn't be bothered to put her ipad down for 2 minutes to fill in her postal vote. Wifi off. She filled it in with another moan about 'annoying mums'. I assumed she spoiled her ballot but she did tell me a few days later that she'd actually voted and hoped her choice gets in.

...do you also control bedtime? Because otherwise the ‘extra 15 minutes of Xbox’ is bullshit.

No NickNacky, my thread wasn't lighthearted, the "forceful" part was.
I do believe that he should vote, as we are lucky to have that right and particularly as he has always been opinionated on the subject of politics and came here hoping that some Mumsnetters might think of some reasons that might persuade him. I wasn't being over-bearing, just hoping for some different ideas.I don't care who he votes for as we probably have different priorities but would rather he spoiled his ballot rather than just not bother!
He had text me to say he'd be a bit late due to a diversion. I text him back and added that he needed to vote tonight so would he rather dinner before or after that. He then replied "Nah, can't be arsed I'd rather be on my Xbox". I replied with a laughing face as I assumed he was joking and he replied "Nah, I'm already going to be late and Mark's waiting for me online." Mark being a friend that he games with. Knowing how stubborn my son is, I knew that I needed a good argument (Let me just clarify - I mean argument as in a persuasive discussion not shouting match, blackmail or punishment for not voting for my party of choice! ) to persuade him to vote and therefore asked for suggestions.
But hey, if that's your idea of being over-bearing...

Honestly, if was him I would just fib and say I’d been - which he probably will do in future - but then I wouldn’t be surprised if you expected follow, I mean accompany him, to the polling station.
