Make up a plausible 2016 map where ...

[⛄]

... the losing candidate wins the bellwethers Ohio, Florida, New Mexico and Nevada.

[⛄]

Hillary Clinton / Martin O’Malley: 313
Jeb Bush / Susana Martinez :     225

[⛄]

Chris Christie / Kelly Ayotte:            270
Brian Schweitzer / Dennis Kucinich: 268

New Mexico isn't a bellwether state

In terms of popular vote, it is:

If you go by popular vote, New Mexico went with the winner in the past 9 elections

No offense to OP, but in 2016 I don't think it would be plausible for either party to win all four states listed and still lose nationally.

I think so, too. Especially the Republican map was extremely hard to create.
If, however, two of the four states are the GOP's candidates' home states, my scenarios will become not completely unlikely.

Yes, that is very true.

Also, having a Brian Sandoval/Susana Martinez ticket might make the Republican map more likely.

However ... I can't see how a Republican can win Florida without a Bush on the ticket.

I've added a poll.
Both maps I created seem pretty much to be the only realistic scenarios.
