I remember him saying in an interview how much he loves working with Patricia Richardson (his wife on the show)
He said they get along great except for their politics.
From her political contributions, I’d say she is a big rat. So that tells me he is on our side

Tim Allen appears to be a Hollywood Republican, a fairly tame species that mainly eats its own. His wife on the current show is Nancy Travis, a lib. The writers are obviously all knee jerk liberal, par for the Hollywood course. The show took a dive this season when they replaced the eldest daughter with an actress who can’t act and looks like a troll. They also gave her a baby daddy who’s a dead ringer ideologically for Meathead on All In the Family, which the producers seem intent on copying.
This is how once-decent sitcoms self-destruct.
