Former Colorado Governor and 2020 hopeful John Hickenlooper forgot what "GDP" - gross domestic product - stood for while he answered a question at a labor conference on Saturday.

"Our gross, whatever that stands for, demographic product," he told a woman at the "National Forum on Wages and Working People."

He was discussing child care and lamented how the U.S. should be able to spend less of its GDP on health care. "You know, I should know that. I can't even remember," he added, in reference to the term's meaning.

Economic issues will likely be a large part of the 2020 election cycle as more progressive candidates like Sen. Bernie Sanders, I-Vt., propose large government programs like "Medicare-for-all."

Hickenlooper consistently lagged behind his fellow 2020 candidates, receiving between 0 and 1 percent of support in multiple polls from April.
