Toby says that industry politics shouldn't play a role in determining the winner, and with the online vote those who've been entertained are naming the artist they think has done the best job.
Keith is one of six stars vying for the ACM's top prize. He's facing Brad Paisley, Keith Urban, Taylor Swift, Miranda Lambert, and Jason Aldean for the honor.
Toby has earned the ACM Entertainer of the Year title twice before, with back-to-back wins in 2003 and 2004. The 46th annual ACM Awards will be presented in a ceremony in Las Vegas, and air on CBS on April 3rd.
Voting for ACM Entertainer of the Year starts TODAY (March 11) at noon PT through April 3 at 5pm PT (www.voteacm.com).
