It was called the "bandwagon effect", a desire to get in on the winner. A fake polling company had been created in a Newfoundland provincial election. On the eve of the polling one party, was given an "insurmountable" lead. That party gained power. Clever stuff, but dirty pool.
My spouse had the "View" on television this morning. I listened to one, Joy Behar and the Whoopster briefly. Mocking what was said to be the original family name of Trump. Said to be Drumpl. Further mention of one Michael Moore to appear on the View. Sickened, I hastened off to the local Tim Hortons for coffee. Leaving,told my spouse that Shakespeare's witches had come to life, presided over by Lady Macbeth. My name for Joy Behar
