DJ Khaled is Muslim.
He's an Obama supporter, and so appears to be a Democrat.
DJ Khaled was born and raised in New Orleans, Louisiana.
With Khaled's Palestinian roots, it should come as no surprise that he's Muslim. He frequently wears a large piece that is the Arabic symbol for Allah. And he's been known to tweet his thanks to Allah. In a particularly thankful post he wrote,
Thank u! Allah! Thank u For everything! We have to give thanks for life every second threw good and hard times ! We so blessed!
Being Muslim is clearly central to his identity. When asked how his culture affects his music, he said,
I represent the Palestinian life–that is who I am. I'm Arab and I'm Muslim. I represent God. I represent love, unity, and peace.
That sums it up pretty well: a Muslim he is.
Go VOTE (for Obama)
Being of Palestinian descent, it seems likely that he's got a view on the Israeli-Palestinian conflict, but I couldn't find anything. I did, however, find out who he voted for in the 2012 presidential election. He wrote about a million–okay, maybe not that many but a lot–of tweets about Obama leading up to the election. On election day he wrote,
Go VOTE for @BarackObama
His Obama tweets don't exactly get into policy matter specifically, and I couldn't find much detail there. But as far as the word "nigga" can be political, he was pulled into that debate. After receiving some criticism for using that word he said,
What makes me mad, 'cause when I grew up, niggas was calling me sand nigga. Now, that's ignorant, because there's only one way to say it. You can't say, 'Yo what up my sand nigga?' . . . When I say 'What up my nigga,' . . . That's just me greeting you with love, but if somebody takes it another way, they dumb, man.
So even though he doesn't have a whole lot to say about politics, I think we can safely call him a Democrat for now.
