Grover Norquist, founder of Americans for Tax Reform, told CNBC's "Squawk on the Street" Monday the presidential election race between Democratic nominee Hillary Clinton and Republican nominee Donald Trump has been focusing more on the behavior, rhetoric and trustworthiness of both candidates rather than their policy ideas.

Norquist said he has been frustrated by the degree to which these issues have been overshadowed by the more sensational aspects of the campaigns. Americans go to the polls Tuesday.

"There's a lot at stake here," he said. "Trump's tax plan is taking the corporate rate from 35% to 15%. The House Republicans are largely in agreement... Hillary's [plan] is a trillion-plus tax increase, no rate reduction [in] business or individual [taxes]. As a matter of fact, every quintile...all do better with Trump's tax proposal. So taxes haven't been discussed."

There are also labor law issues that haven't been discussed enough, in Norquist's opinion. He mentioned Clinton's desire to crack down on independent contracting and said investors should pay attention to the stock prices of any company that structures as a franchise if Clinton is victorious.

"If you're invested in a franchise company, you're in big trouble if Hillary is there because she'll keep the [National Labor Relations Board] the way it is and they want to make every McDonald's (MCD) manager an employee and every McDonald's local employee an employee of corporate. Easier to sue, easier to tax and you destroy the franchise structure in the U.S.," Norquist said.

CNBC's Carl Quintanilla asked Norquist if he received a signed pledge from Donald Trump vowing not to raise taxes. "No, he's not signed the pledge," Norquist responded.

"He has not publicly signed the pledge and when we've asked for it we don't have it," he added. "He has not made a commitment not to raise taxes. He has committed to a significant tax cut first thing, which is good and healthy. But he has not yet made a commitment to the American people never to raise taxes."
