Thomas Sowell, a leading intellectual who has been on the frontlines of the conservative movement for decades, is endorsing Ted Cruz as his choice to be the next President of the United States.

Writing in RealClearPolitics, Sowell explained that “the vacancy created on the Supreme Court makes painfully clear the huge stakes involved when we choose a President of the United States.”

“Given the advanced ages of other justices, the next president is likely to have enough vacancies to fill to be able to shape the future of the court that helps shape the future of America,” Sowell added.

Sowell castigated the “frivolous rhetoric and childish antics” seen in the recent Republican debates.

“If ever there was a time to choose a president with depth, rather than glitter or glibness, this is it,” he commented.

The conservative intellectual revealed he is no fan of Republican nominee Donald Trump.

“Some seem to think that Donald Trump’s lead in the polls and in the New Hampshire primary make him the most electable candidate, even if he often acts like an overgrown spoiled brat,” he opined. “But the fact that Trump leads in the polls does not mean that he is electable in the general election this fall. He is ahead only because the majority vote among Republicans has been split among so many other candidates.”

Ultimately, Ted Cruz is Sowell’s choice, because Marco Rubio has “no comparable experience,” he states.

“As someone who once clerked for a Chief Justice of the Supreme Court, he will know how important choosing Justice Scalia’s replacement will be. And he has the intellect to understand much more,” Sowell concluded.
