Today’s idiom is:
WIN BY A LANDSLIDE
It looks like that candidate will win by a landslide.
No the candidate wasn’t actually in a landslide, although politicians will do just about anything to get a vote!
We use this idiom to say: get most of the votes; win by a large margin
This idiom comes from the idea that a landslide, which is rocks and dirt sliding down a mountain or hill, builds momentum and cannot be stopped.
As the presidential campaigns ramp up for the election November of 2016, this is a idiom you may hear often!
