Well, sort of. There were several states that Democrats traditionally won federally, but those weren't the "safe" ones like new York and California. The big thing Trump took from the Democrats was the Rust Belt states - the old industrial places like Michigan, which usually vote for Democratic Party presidents but have strong Republican contingencies and often have Republican governors.

The difference is that the Democratic party "rebased" itself. They've basically removed blue collar white people as a constituency that they focus on.

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.

No, no, no, she lost because of Russian hacking! /s

Not really. Both bases stayed pretty true to their colors.

That's a slight simplification. There where over 200 counties that voted for Obama twice and now voted for Trump.

Right i wasn't including those in the "bases". 200 counties represents about 6% of the total number of counties in the country, and few of them are from states that "always vote for democrats"
