Washington (CNN) Former 2016 Republican presidential candidate Jeb Bush said he thinks a Republican should challenge President Donald Trump in next year's election, arguing the party "ought to be a given a choice."

"I think someone should run. Just because Republicans ought to be given a choice," said Bush, who also served as the governor of Florida, in an interview with David Axelrod that will air Saturday on "The Axe Files." He added that beating Trump in 2020 will be difficult for anyone because "he has a strong, loyal base" and "it's hard to beat a sitting president."

"But to have a conversation about what it is to be a conservative I think is important," he added. "And our country needs to have competing ideologies that people -- that are dynamic, that focus on the world we're in and the world we're moving towards rather than revert back to a nostalgic time."

Bush's comments came as he was discussing Maryland Republican Gov. Larry Hogan, whose inauguration speech in January caused some to question whether or not he was eyeing a 2020 bid.

In his own speech at the inauguration, Bush lauded Hogan, regarding him as being "at the top of a list of leaders that I admire today because what's happening here in Annapolis is the antithesis of what's happening in Washington, DC, these days."
