Donald Trump's inauguration may have certain segments of society worried, but those most immediately affected will be D.C. nightclub owners.
It doesn't take a rocket scientist ... hoards of celebs were planning to descend on D.C. to party hard, celebrating what they thought would be the first woman prez. Our survey of the Capital and Hollywood presents a pretty clear picture ... celebs are staying home.
One of the top clubs -- The Park -- attracted Jamie Foxx, Beyonce, Jay Z and Diddy for Obama post-inauguration parties. But the club's owner, Marc Barnes, tells us celebs will likely shy away this year.
Ditto for Echostage -- a nightclub/concert venue -- which had Hillary events penciled in, but now it has nothing.
But here's the reality you'll hear from real Washington insiders ... Republicans actually party harder than Dems ... so even if celebs stay away, it could be a good time.
