Intellectual Qualifications

"Intellectual qualifications" for presidential candidates might include the following: 

• Certifiable IQ score
• Certifiable psychological, behavioral assessment
• Academic studies and achievements
• Professional behavior

What we citizen-voters are looking for are indications about mental, cerebral, cognitive, psychological abilities for which we need professional guidance. Advice such as that should come from vetting and verification performed by third-parties that may be sponsored by the hosting political party.

Behavioral characteristics desirable for a presidential candidate are discussed in my book: How to Select an American President by James A. George with James A. Rodger (c) 2017 Archway Publishing.

In the instance of Donald Trump, he has a professional reputation for being a con artist and a cheat.

"I’m a New Yorker, and New Yorkers know a con when we see one! Trump says he’ll punish manufacturers that move to Mexico or China, but the clothes he sells are made overseas in low-wage factories. He says he wants to put Americans back to work, but he games the US visa system so he can hire temporary foreign workers at low wages. He says he wants to deport 11 million undocumented people, but he seems to have no problem in hiring them. What’d I miss here?! 

Truth be told, the richest thing about Donald Trump is his hypocrisy. He wants you to believe that we can solve our biggest problems by deporting Mexicans and shutting out Muslims. He wants you to believe that erecting trade barriers will bring back good jobs. He’s wrong on both counts."

Today's News contains this:

"David Jolly, a former Republican congressman from Florida, stunned a CNN panel on Monday morning when he said President Donald Trump isn’t “intellectually qualified” to be president. 

When asked by CNN’s Poppy Harlow whether Trump should publicly apologize if it’s revealed that he was wrong in accusing former President Barack Obama of wiretapping Trump Tower during the 2016 election, Jolly said that he should — but he also said that an apology wouldn’t mask Trump’s other major shortcomings as president." 

“There’s a bigger issue, whether this president is intellectually qualified to be President of the United States,” Jolly said."

Trump lies 63% of the time.
