Senate
Two new polls were released in the red-hot Texas US Senate Republican runoff between Sen. John Cornyn and Attorney General Ken Paxton and the results are identical.
Peek Insights conducted its survey for Texans for a Conservative Majority, a Super PAC that supports Sen. Cornyn (April 6-9; 800 likely Texas voters), and the co/efficient polling firm, in an independent release (April 11-14; 1,143 likely Texas Republican runoff voters; text and live interview), each find Sen. Cornyn leading AG Paxton by a narrow 44-43 percent.
The surveys provide underlying good news for Sen. Cornyn, however. In the primary, polling consistently found Paxton leading the race. In fact, from the final six publicly released pre-primary polls, the Attorney General led the Senator by an average of seven percentage points. In the actual election, Cornyn topped Paxton by one percentage point, meaning the pollsters underestimated the Senator’s Republican primary position by eight full points.
Therefore, if a similar under-counting of Cornyn’s support is again present in the latest data, it is possible that the Senator’s lead is greater than the one percentage point that both pollsters currently detect.
Included in co/efficient’s data release are their crosstabs, which reveal some interesting points.
While the two candidates are virtually even in support among the likely May 26 runoff voters, the co/efficient segmentation allows us to see where each candidate can target and improve.
Possibly the most surprising finding is that Paxton enjoys a 14-point advantage among self-identified Christians. Considering Paxton’s well-publicized extra-marital affairs that led to his wife filing for divorce, one might expect his personal behavior to be a negative factor within this group.
Therefore, expect the Cornyn campaign to improve the Senator’s standing in this sector as the campaign moves toward culmination in late May.
While most segments show the candidates at parity as does the actual ballot test, the two candidates do enjoy advantages within certain groups pertaining to turnout propensity.
Among the respondents who have voted in four of the last four and three of the last four elections, obviously those with the highest vote propensity, Paxton claims a four-point advantage. Sen. Cornyn posts a three-point edge among those with moderate voting propensity — the two of four categories — while Paxton has the advantage among those most likely not to vote.
The other traditionally high-vote propensity group, those over 65 years of age, favor Cornyn by four points. The Senator also has the edge with those aged 18 through 54, but Paxton posts a double-digit advantage within the 55-64 age sector.
The fact that most of the age segments favor Cornyn by an average of four points, yet Paxton dominates the 55-64 group by 19 points fails to make sense. Therefore, it is probable that his very large margin is an anomaly.
The runoff will prove to be a battle between the urban and rural areas. In the primary election, Cornyn won in the state’s largest metro areas, meaning Harris County (Houston), the Dallas-Ft. Worth Metroplex, San Antonio-Austin I-35 corridor, and the populous region along the Mexican border then north to the Corpus Christi area. Paxton was strong throughout the state’s rural areas both in East and West Texas.
While a great deal of money and campaign time will be spent between now and the May 26 election, with heavy emphasis on the early voting process scheduled during the May 18-22 period, the winner will be the candidate whose campaign best energizes its primary election supporters to come back and vote again in the runoff election. Typically, Texas runoff elections turn out about two-thirds of the number who voted in the primary.
May will be an interesting month for vulnerable Republican Senators. Just before the Texas runoff, Louisiana Republican voters will largely determine Sen. Bill Cassidy’s fate in the May 16 partisan primary vote. Some polls show Cassidy trailing both of his Republican challengers — Rep. Julia Letlow (R-Start) and state Treasurer John Fleming. Therefore, the Louisiana and Texas intra-party elections means late May will host a very intriguing political period.
