Earlier quoted context omitted.
Not really a fair statement given the oddities of the electoral college. I know a lot of people in big coastal cities (New York, Boston, LA, San Fransisco, Seattle) who don't vote but are very anti-Trump. They know it doesn't matter because their states were always going to go strongly for the Democrats.
I'm not from the U.S., so my knowledge here is a bit sketchy, but wasn't one of the problems Clinton had exactly that some states which always voted for the Democrats fell to the Republicans this time?
This created a problem, as the get out the vote efforts from groups like unions and others were tepid as a result, and the GOP isn't stupid and courted these voters pretty heavily. The other thing is that the Democrats over-relied on minority voters as a key base, which didn't work out for a variety of reasons.
I think strategically they missed the fact the ethnic voting requires an ethnic candidate. They also missed that certain key platform positions alienate ethnic factions of their voting base. In the old days, the Irish-Catholic political machines didn't run aging teetotaler baptists as candidates for a good reason!
Basically, Mrs. Clinton ran a campaign that was divided, disorganized and poorly administered, which crippled her ability to make appropriate decisions. Trump's opportunism, marketing savvy, and tight team made his campaign agile and tightly focused on the objective. When the campaign had internal divisions, he purged the dissenters and moved on.
