Hillary Clinton led Donald Trump...

...by about five points in February. Yeah, you're probably thinking, So, what? The most recent polls show the race in a dead heat.

Well, according to Sam Wang,* a professor at Princeton (my emphasis):

Amusingly, national polls won’t reach their February levels of accuracy until August. The Clinton-Trump margin in February was Clinton +5.0%. So how about if we just use that until after the conventions. Can you wait?

What's more, Professor Wang thinks by November it will be Clinton +6.5%.

* Who the heck is Sam Wang? He's the guy who pretty much got it perfect in 2012.
