Conor McGregor's a living legend to his Irish fans … but Ireland's 2nd biggest UFC star says he is NOT cut out for a political career back home.
We asked "Irish" Joe Duffy about McGregor pulling a Trump when his fighting days are done — something Conor teased when we got him out in NYC last month.
Joe — who fought and beat Conor back in the day — was super complimentary of McGregor as a fighter, but told us why a run for office wouldn't end well for him.
"In Ireland, people are quite humble," Duffy told TMZ Sports, "Cockiness isn't a trait they generally take to."
Joe also told us he couldn't see Conor campaigning for a fight against Khabib Nurmagomedov — the scariest dude in their division right now … and he made some pretty good points.
Duffy ain't the only one who feels that way … lightweight contender Justin Gaethje basically sang the same tune when we spoke to him recently.
