Despite the fact the actress has remained silent thus far, a GOP political action committee has already taken out ads attacking Judd for living in Tennessee, not in her home state of Kentucky.
ABC News is among those reporting that Judd is set to announce her democratic candidacy against Senate Republican incumbent Mitch McConnell. The timing, however, remains unclear.
Judd, a professed Obama supporter and international humanitarian, has never run for office before.
