A new study reveals that a higher number of incumbents are losing primaries in state legislative races throughout the United States -- and Texas has contributed to the trend.
Seven incumbent Republican members of the Texas House of Representatives lost primaries, including three committee chairmen. The number may rise, with four more House races and one Senate seat in play for the runoff election on Tuesday.
The rate of incumbent losses this year, 14.8 percent, has outpaced the rate in 2010, 8.38 percent, Ballotpedia found in a recent review of the matchups.
In 2012, 76 of 513 incumbents lost in their primaries. In 2010, 95 of the 1,133 incumbents lost in that round.
In Texas, the upsets have been attributed to redistricting and Tea Party influence.
"The Tea Party has done a better job here of organizing and turning its voters out, and that's the story," Jim Riddlesperger, a political science professor at Texas Christian University, told the Fort Worth Star-Telegram after the primary.
The defeat of three lieutenants of House Speaker Joe Straus in the May primary underscores the volatility for incumbents in certain Texas House races.
These lawmakers served as House committee chairmen.
Throw in a Texas Senate race, and political junkies have some excitement.
