A new poll suggests Lt. Gov. Casey Cagle may not be able to avoid a runoff in Georgia's primary elections.

The February Mason-Dixon Poll shows Cagle may fall short of the 50 percent of the vote required to avoid a runoff, despite being the leading contender in the Republican gubernatorial primary.

The poll includes a sample of 500 likely Democratic primary voters and 500 likely Republican primary voters.

Cagle tops Republican polls with a double-digit lead over other candidates at 27 percent of likely primary voters' support, according to the poll. Brian Kemp, Clay Tippins and Hunter Hill essentially tie for second place at 13, 12 and 11 percent, respectively. Michael Williams (5 percent) and Alan Urbach (1 percent) trail behind, and another 31 percent of likely voters remain undecided.
