In the near term, Trump's plans would provide the bigger goose for the economy, due to his aggressive tax cuts, but that would be mitigated down the road by a higher debt and deficit load, according to the group's most recent analysis released Monday.
As for Clinton, her tax increases would help boost fiscal health, but her spending plans on net would increase the national debt by $200 billion over 10 years. (Clinton repeatedly has said her spending platform is paid for, but virtually all independent analyses find her proposals would result in a slight debt increase.)
Trump's plan to repeal Obamacare would stimulate growth by incentivizing work, but overall his tax cuts would add $5.3 trillion to the debt, under numbers the committee arrived at using its own calculations and research by the Tax Policy Center. Trump has pledged that economic growth through lower regulation, decreased energy costs and elimination of the U.S. trade deficit would make the tax cuts revenue-neutral.
"A rapid acceleration of growth also leads to a significant reduction of our debt burden relative to GDP, and when Mr. Trump's spending cuts are added the plan achieves full revenue neutrality," Trump economic advisor Peter Navarro and businessman Wilbur Ross wrote in Tuesday's Wall Street Journal.
In a subsequent interview, Navarro dismissed the CRFB as a "sham group, because they don't really have any original analysis of their own." He said the committee relies on the Penn Wharton model, which doesn't take into consideration offsetting effects.
"It's analytical malfeasance at best and political malfeasance at worst," Navarro said.
