Before we get into the actual numbers its good to understand the rules around Primary races. These are documented in the
TEXAS ELECTION CODE
TITLE 10. POLITICAL PARTIES
SUBTITLE B. PARTIES NOMINATING BY PRIMARY ELECTION
CHAPTER 172. PRIMARY ELECTIONS
SUBCHAPTER A. NOMINATING BY PRIMARY ELECTION GENERALLY

There is this very important rule which states:

Sec. 172.003.  MAJORITY VOTE REQUIRED.  Except as otherwise provided by this code, to receive a political party's nomination, a candidate in a primary election must receive a majority of the total number of votes received by all the candidates for the nomination.

 

Acts 1985, 69th Leg., ch. 211, Sec. 1, eff. Jan. 1, 1986.

So you have to have a majority of the total number of votes received by all the candidates, NOT all the votes cast and I have both percentages below in the spreadsheet so you can see how that works out.

In all of the contested races there was only one race where someone had a majority and that was Jeff Slaton who is now the Republican nominee for Constable, Precinct 2, Unexpired term. Congratulations to Jeff!

The other contested races did not have a majority so there is this other rule which dictates what happens

Sec. 172.004.  RUNOFF PRIMARY.  (a)  If no candidate for nomination to a particular office receives the vote required for nomination in the general primary election, a runoff primary election shall be held to determine the nomination.

(b)  The candidates in a runoff for a nomination shall be determined and a tie vote in a runoff resolved as provided by Subchapter B, Chapter 2, for a runoff for an election to office.

 

Acts 1985, 69th Leg., ch. 211, Sec. 1, eff. Jan. 1, 1986.

So now we have to have a Runoff Primary Election but hey how do you determine which candidates get to participate in the runoff? Well there is another rule but it is in a different part of the
TEXAS ELECTION CODE
TITLE 1. INTRODUCTORY PROVISIONS
CHAPTER 2. VOTE REQUIRED FOR ELECTION TO OFFICE
SUBCHAPTER A. ELECTION BY PLURALITY

Sec. 2.023.  RUNOFF CANDIDATES.  (a)  Except as provided by Subsections (b) and (c), the candidates in a runoff election are the candidates who receive the highest and second highest number of votes in the main election or who tie for the highest number of votes.

(b)  If more than two candidates tie for the highest number of votes in the main election, an automatic recount shall be conducted in accordance with Chapter 216.  If the recount does not resolve the tie, the tied candidates shall cast lots to determine which two are to be the runoff candidates.

(c)  If two or more candidates tie for the second highest number of votes in the main election, an automatic recount shall be conducted in accordance with Chapter 216.  If the recount does not resolve the tie, the tied candidates shall cast lots to determine which one is to be the second candidate in the runoff election.

(d)  The presiding officer of the final canvassing authority for the election shall supervise the casting of lots under this section.

 

Acts 1985, 69th Leg., ch. 211, Sec. 1, eff. Jan. 1, 1986.  Amended by Acts 2003, 78th Leg., ch. 652, Sec. 2, eff. Sept. 1, 2003.

and there is an important note for those who voted in the Democratic Primary, you will NOT be able to vote in the Republican Runoff Primary so don't waste your time trying, here's the rule that says so

Sec. 172.125.  ADDITIONAL PROCEDURE FOR ACCEPTING VOTERS IN RUNOFF.  (a)  For a runoff primary election, the voter registrar shall enter on the list of registered voters a notation beside each voter's name indicating the preceding party primary for which the voter was accepted for voting, if any.

(b)  An election officer at a runoff primary election polling place shall determine whether the name of a voter offering to vote is noted on the list as having been accepted for voting in another party's primary.  If the voter's name is so noted, the voter may not be accepted for voting at the runoff unless the voter executes an affidavit stating that the voter did not vote in the primary or participate in a convention of another party during the same voting year.

 

Added by Acts 1993, 73rd Leg., ch. 728, Sec. 67, eff. Sept. 1, 1993.

So now that we know how to determine who is going to be in the Runoff Primary Elections let's take a look at the numbers
