Rep. Doug Miller (R-New Braunfels) did not win a three-way primary outright and faces Fredericksburg hardware store owner Kyle Biedermann in the Republican runoff. Since 1996, just four of the 22 legislative incumbents forced into runoffs have prevailed, and all but one of them finished at least 17% ahead of their rival in the primary. Miller was 3.6% ahead of his runoff opponent.
Miller finished first in the primary, receiving 43% of the vote. Biedermann finished a close second with 40%. A third candidate, Boerne attorney and anti-Sharia Law activist Chris Byrd, received the remaining 17%.
