2. Maybe you should check out the current betting odds on Real Clear Politics and FiveThirtyEight. Ms. Clinton IS 50+ points ahead. (Note: this is why neither of these two sites...which were all the rage on here when the polls were tightening are no longer mentioned.)
You need some remedial math.
One set of data - "points" - represents the percentage of likely voters who will vote for her. 75-25 is 50 "points" of likely voters. A percentage of the VOTE.
The 538 set of data is betting odds - the likelihood that she will WIN.
Let's make it simple - if she wins by ONE POINT - she has a 100% "chance" of winning. Got it? Nate Silver's odds are winning odds - she may win by 10, 20 or half a point.
It's not a point spread - they run a bunch of weighted scenarios and reckon the likelihood of winning.
If you STILL don't get it, come back here and I will try to make it even SIMPLER.
Because since we're all morons, maybe I can't make it easier to understand.
