I hope that helps!
Earlier it looked like no one could challenge incumbent Jim Plowman, but CA Plowman has done a very unethical thing that has brought to light that he may be corrupt and vulnerable. Plowman pressed charges against Mark Tate this Spring in the middle of a hotly contested Republican party primary election, effectively knocking Tate out of the race and handing Jill Vogel the nomination to run for State Senate as a Republican. Now, six months later, the trumped up charges have been dropped. Meaning Tate was innocent all along, should probably have been given the nomination against Vogel and that Plowman is abusing the power of his office to impact politics.
Please take the time to research this and decide for yourself.

Also - be aware that many Loudon County Supervisors are very corrupt and getting HUGE campaign contributions from developers (Snow, Staton, Delgaudio) - please consider very carefully if you want them to remain in office.
You can look up contributions via VPAP.org for any candidate.
