The three senators who sent the fewest bills to Gov. Greg Abbott's desk this session: Bob Hall, R-Edgwood (left), Konni Burton, R-Colleyville (middle) and Don Huffines, R-Dallas (right).

The three state senators who had the least impact duringย the 2015 legislativeย sessionย โ€” at least in terms of numbers โ€” were all freshman conservatives from the Dallas-Fort Worth area.ย But observers say that doesnโ€™t mean they had an unsuccessful session.

Among the three Republicans, Konni Burton sent justย one bill to Gov. Greg Abbott‘s desk, while Don Huffines and Bob Hall passedย none. No other senator passedย fewerย than seven bills, and state Sen. Judith Zaffirini, D-Laredo, topped the rankings with 44. (Former Sen.ย Leticia Van de Putte passed no bills, although she stepped down to run for San Antonio mayor.)

Yet statistics on bills’ passage, said Rice University political scientist Mark P. Jones, can be an incomplete measure.

โ€œItโ€™s one of many indicators of legislative success, but itโ€™s not the only one,โ€ Jones said. โ€œCertainly you can be very influential without passing many bills. A great example of that at the national level is [U.S. Sen.] Ted Cruz.โ€

Getting your bills signed by the governor is equivalent to hitting a home run, but Jones noted there are โ€œa lot of ways to score runs in baseball.”

One, asย Burton, R-Colleyville, demonstrated, is tacking on your legislative priorities as amendments to other bills. Burton resorted to that tactic when longtime state Rep. Tom Craddick, R-Midland, killed some of her billsย afterย she led efforts to block his proposal that would have banned texting and driving statewide.

With her legislation facing little hope, Burton got some of her ideas to Abbottโ€™s desk as amendments, andย Senate staff dubbed one bill with several Burton amendments the โ€œKonnibus bill.โ€ That effortย demonstratedย the freshmanโ€™s โ€œability to maneuver legislatively with the best of them,โ€ according to Burtonโ€™s chief of staff, Art Martinez de Vara.

In an emailed statement, Burton said itโ€™s โ€œamazing what you can accomplish when you donโ€™t care who gets the credit.โ€

โ€œWe were able to pass our legislation and kill [Craddickโ€™s], seems like we got what we wanted, and what is best for the people of Texas without playing the political gamesmanship that dominates the Capitol,โ€ Burton said. The one bill Burton passed established a pilot program to recycle unused prescription drugs.

Hall, meanwhile, garnered aย โ€œFurnitureโ€ award inย Texas Monthlyโ€™s ranking of lawmakers, a designationย given to those whose โ€œparticipation in the legislative process was indistinguishable from that of their desks and chairs.โ€

Huffinesโ€™ predecessor โ€” whom Huffines beat in a GOP primary โ€” called him โ€œthe least effective of all 31 senators.โ€

โ€œTo serve his constituents, heโ€™ll need to temper his strict Libertarian and Tea Party views and better understand what it is to be a legislator,โ€ former state Sen. John Carona said in a statement. โ€œScorecard results mean nothing if Donald canโ€™t work with his colleagues to get things done.โ€

Hall, R-Edgewood, and Huffines, R-Dallas, did not respond to requests for comment.

But in the view of conservative groups, all three senators had a strong session.

The three ranked in the top four of the Empower Texans 2015 Fiscal Responsibility Index. In a blog post titled โ€œFreshmen Lawmakers Deliver Results,โ€ the group noted that Huffines โ€œblazed a conservative trailโ€ and Hall โ€œvalidated the grassroots effort that supported his election.โ€

The group also wrote that thereโ€™s little chance Texans could โ€œfind a stronger fighterโ€ than Burton, who replaced Wendy Davis, the Democrat who unsuccessfully ran for governor.

The three senators got similar praise from Emily Horne, a lobbyist for Texas Right to Life, who said they took the unusual step of co-authoring all of herย groupโ€™s priority bills, and were proactive in backing their issues.

โ€œThey were fantastic,โ€ Horne said. โ€œWe were thrilled to work with them. They were supportive and wanted to do anything they could to help. We hope they continue to work with us in future sessions and hope to see them again.โ€

Next session, the three political newcomers will have more legislative experience, unlike some other freshman senators who had previously served in the House, said state Sen. Royce West, D-Dallas.

โ€œI think that having one session under their belts could help them as it relates to knowing how the process works,โ€ West said. โ€œNow, theyโ€™re going to have to make a political decision as to whether or not theyโ€™re gonna work with other senators in order to pass legislation and thereby deal with issues not only for the state of Texas but for their districts.โ€
