2012 Republican presidential nominee Mitt Romney has yet to officially endorse a presidential candidate in this election cycle, however, he is now calling for the Libertarian party to be included in the presidential debates this fall.

Romney posted a tweet Wednesday afternoon, saying he hopes to see Libertarian presidential nominee Gary Johnson and his running mate, Bill Weld on the debate stage alongside Trump and Clinton.

Throughout the course of the election, Romney hasn’t been quiet about his dissatisfaction with both the GOP and Democratic candidates. He has even suggested that he may cast his ballot for the Libertarian ticket on Election Day.

“If Bill Weld were at the top of the ticket, it would be very easy for me to vote for Bill Weld for president,” Romney told CNN earlier this summer.

In order to appear in the debates, Johnson and Weld must garner at least 15 percent support nationally in five recent public opinion polls. Johnson is, at present, the closest third-party candidate to that threshold.

The latest RealClearPolitics average has Johnson with 8.6 percent support. In August, one poll showed the former New Mexico governor with 12 percent support, and another showed him polling at 11 percent.

According to a report from The Hill, it seems 3 candidates on the debate stage is a real possibility. All three debate venues have indicated they are preparing a third lectern just in case Johnson and Weld are able to reach 15%.

The first debate is scheduled for Sept. 26 at Hofstra University.
