Her husband was born in Michigan. I think their failing Hollywood careers brought them to his home state.
The history on this kind of stuff is not good.
Nancy Kulp (Jane Hathaway from The Beverly Hillbillies) moved back to Pennsylvania to run as a Democrat, got her head handed to her by Republican Bud Shuster (with some help from hilarious radio ads featuring Buddy Ebsen. Kulp never spoke to him again).
Joe Flynn (Capt. Binghamton from McHale’s Navy) moved back to his hometown of Youngstown, Ohio to run as a Republican (yeah, we know how THAT worked out...he passed away not long afterwards)
More recently Clay Aiken got stomped in North Carolina.
Of course we did elect a Gopher (Love Boat) and a Cooter (Dukes of Hazzard) to Congress at one time.
