Colorado Gov. John Hickenlooper, a Democrat, and Ohio Gov. John Kasich, a Republican, are considering mounting a campaign on a nonpartisan presidential ticket in 2020, with Kasich in the top spot, according to reports.

The two governors have been appearing together for months at national events and on cable news programs urging President Trump and leading Republicans to consult both sides of the aisle and the nation’s governors to resolve problems with the nation’s health care system.

Hickenlooper downplayed a suggestion the duo might join together for a presidential run earlier this month at a discussion in Denver sponsored by Politico, but he didn’t rule out the possibility.

But a source close to the discussions told CNN that the two governors have recently eyed the possibility of forming a national unity ticket and running running for the White House as independents, although the source emphasized that the talk has so far only been casual, CNN reported Friday morning.

“The idea of a joint ticket has been discussed, but not at an organizational or planning level,” the source, who spoke on condition of anonymity, told CNN. “What they are trying to show the country is that honorable people can disagree, but you can still problem solve together. It happens in businesses and it happens in families. Why can’t it happen in Washington?”

Axios co-founder Mike Allen was first to float the possibility Friday, reporting that the two governors – “the Johns” – plan to broaden their joint policy talk from health care reform to immigration and job-creation proposals.

The two are also in discussions with media giants about starting a podcast or cable show “to continue cementing their brand,” Allen reported.

Some Democrats, however, are “apoplectic” about the thought of Hickenlooper, who made the short-list for Democrat Hillary Clinton’s vice presidential pick last year, joining forces with Kasich, who lost his bid for the GOP nomination to Trump, Allen reported.

But Axios also quotes a “veteran operative” who sounded supportive of the plan, saying, “Something big and historic needs to happen to break the logjam.”

A spokeswoman for Hickenlooper didn’t immediately respond to an inquiry from Colorado Politics about the possible alliance.
