If your side wins,
“The people have spoken! Hail their wisdom!”
The result can only be a ringing endorsement of your policies and not a default vote to keep the other, even worse mob out.
If your side loses,
“The people were conned! Pity them their stupidity.”
The only introspection you are allowed is into how you failed to get your message across. Of course they would have supported your policies if only they’d understood them, poor lambs.
