In Western Kentucky, there are several big races for judge executive, jailer, county attorney and other county-wide elected positions.
But the race grabbing national attention is the race for US senate.
Senate minority leader, Mitch McConnell, still holds a commanding lead over Republican challenger, Matt Bevin, as the primary race enters its last leg.
The latest Bluegrass poll found 55% of likely GOP voters support McConnell, while 35% favor Bevin.
That same poll suggests a November match-up between the five-term incumbent and Democrat Secretary of State, Alison Lundergan-Grimes, could be an airtight race.
Grimes is facing token opposition in Tuesday's primary election.
