A politician pictured holding a pint of lager and watching the football is just like you.
He’s a normal person. He drinks pints of lager. You drink pints of lager. He also watches football, like you do.
If you look at the photo, he seems happy, perhaps someone has just scored a goal? When someone scores a goal, you’re happy about it as well. You and the politician are quite clearly alike.
“Well, this picture of a politician holding a pint of lager and watching the football certainly challenges my perception that he exists in a rarefied world of expenses, fine lunches, arcane parliamentary procedure, and deranged ambition,” you think, on seeing the picture.
“If he likes a pint of lager and watching the football, like I do, then perhaps he even does some of the other things I do, like going to the shops and washing my car. We clearly have a lot in common. Perhaps he understands me and people like me.”
After seeing the picture of the politician holding a pint of lager whilst watching the football, you have become slightly more inclined to vote for him.
He may be a naked opportunist, prepared to exploit any situation to further his own ambition. He may be harbouring terrible, terrible, borderline racist views and be supportive of policies that will make you and many like you considerably worst off.
He may be all of those things, but he also drinks a pint of lager whilst watching the football, just like you.
