Race uncontested after Nichols’ win in the Republican primary.
Incumbent Democratic Senator Ken Armbrister did not run for re-election. No other Democrat ran to replace him, allowing Republican Glen Hegar to easily win the race, flipping the seat.
Incumbent Frank Madla was ousted by Uresti in contentious Democratic primary race. Madla was the only incumbent senator to lose a primary race in 2006.
This was considered by some to be an extremely important Texas Senate election race.[2] Thought to potentially add to the competitiveness of this Senate race was District 29's historically low-voter turnout and Republican "Dee" Margo's close connections to President George W. Bush via First Lady Laura Bush's close friendship to "Dee" Margo's spouse, El Pasoan Adair Margo. As it turned out, Shapleigh won reelection in a race that was not that close.
