If "everything you read" indicates HRC would be a "big favorite," you need to expand your reading scope.
As for the conclusions drawn above about minorities, it's a crap shoot. They vote (generally) like lemmings, but won't come out if, for example, it's raining on election day. This is why Democrats are so keen to promote absentee ballots - it's easy to cheat, and they don't depend on unpredictable November weather.
Nevertheless, the key to this election will not be "Blacks" or "Hispanics," but rather, working-class White People. If they can be mobilized, their numbers will overwhelm the teat-sucking minorities who flock to the Democrat candidate, no matter how repulsive. Everything Trump says is geared to mobilize working-class white people. It may be offensive to those with delicate sensitivities, but to the guys down at the pool hall, Trump is saying EXACTLY what they want to hear. Make America great again. Get rid of the illegals. Build a wall. And so on.
What I think is interesting is that 6-12 months ago, the Democrats in Washington were willing to bet their cushy government pensions on HRC being the next President, but now...
...they are apoplectic about the possibility that Scalia's replacement will be nominated by the "next President."
Guess they are no longer so sure that it will be Hildebeast.
Don't bet the farm.
