Most parts of the US are close enough that a "major victory" or a "guaranteed outcome" is measured at the level of a few percentage points. Even in the hopelessly gerrymandered house elections coming up in 2018 there may be as many as 70 seats in play, precisely because even a "safe" seat is only safe by a comparatively small percentage margin.

Geographically, "most parts of the US" are fairly close. If you live in one of those parts, vote accordingly.
By population, that's substantially less true - nothing I do in the ballot box is going to make a dent in a 60-40 split in CA, and quite a few will have to think just like me before it does. If you're in one of those parts, vote accordingly.
My third party vote in CA arguably has a bigger effect than a major party vote in CA, for the presidency in the general election.
