Thursday night's Republican debate, the eleventh for the GOP, was a knock-down, drag-out spectacle featuring pugnacious and frequently vulgar candidates.

On stage in Detroit, real estate mogul Donald Trump faced off against his three remaining Republican challengers in the presidential race: Senator Marco Rubio of Florida; Ted Cruz, the senator from Texas; and John Kasich, the governor of Ohio. The candidates tore at each other over policy and strategy for leading the nation, throwing out accusations of cheating and lying, and even insulting each other's individual physiology.

As usual, high-profile business owners were very vocal about what they saw, via social media. Shark Tank host Mark Cuban didn't offer a new opinion, but still expressed where his allegiance lies. Here's a round-up of tweets and other posts.

Tesla and SpaceX founder Elon Musk sought to distance himself from the political race altogether, and defended himself against a claim that SpaceX is among the top donors to Donald Trump's campaign:

Finally, Sandy Lerner, the co-founder of Cisco Systems, had this observation about the debates and the presidential election cycle so far, sent by email:

"When was the last time we voted for ANY politician we could trust?...Does anyone REALLY trust Donald Trump?"
