Then Kentucky was not a union state at the start of the war. Neither was New Mexico Territory, Arizona Territory.
There were confederate supporters in Missouri and in Maryland as well that controlled parts of those states at the start of the war.

And Jefferson Davis sent a personal letter to Magoffin one week earlier promising that confederate troops would stay out of Kentucky.And when the state legislature passed a bill demanding the confederate forces leave the state, Magoffin vetoed it, a veto that over overridden. Eventually his pro-confederate stances made his position untenable, given the overwhelming pro-union sentiment in the legislature, and he resigned.
