Useful to be reminded how many people don’t vote. The polls are always about likely voters; they don’t include those who won’t vote. So the 50:50 split is a nonsense; neither party likely has more than 1/3 of the electorate behind them, with a whole 1/3 disengaged from the whole thing.
The in- in inflammable means “to cause to be”. Like indebted or indent. Flammable and inflammable are actually subtly different words, they dont mean exactly the same thing although often used interchangeably now.
