The historic political drama that played out over the weekend is expected to affect other races in November as frustrated voters who weren't happy with either choice for president weigh new options.
Elected leaders in Houston and across Texas are now shifting their focus to Kamala Harris after President Joe Biden and other Democrats endorsed her to replace him on the ballot.
Late Monday afternoon, Trey Martinez Fischer, the chairman of the Texas House Democratic Caucus, announced that the Texas delegates who represent 13 million voters are backing Harris.
Meanwhile, Senator Ted Cruz, who's locked in a heated battle with Democratic challenger Colin Allred, was in Houston on Monday where he linked his opponent to Harris, Biden.
"As the border czar, that's Joe Biden's term, not mine, she [Harris] bears direct responsibility for the chaos at the southern border,” Cruz said. "I want to tell you who also bears full responsibility for the disastrous policies of Joe Biden and Kamala Harris, and his name is Colin Allred."
Allred was also in Houston where he spoke to the American Federation of Teachers.
"Here in Texas and across this country, we can't afford six more years of Ted Cruz's divisive politics," Allred said. "With y'all's help and with God's grace on November 5th, I'm going to beat Ted Cruz and become the next United States senator in the great state of Texas."
The Dallas Congressman didn't mention Harris in his speech but a campaign spokesman said he is backing her.
In a post on X, Allred also thanked Biden for his decision "to put country before self."
KHOU 11 political analyst Bob Stein, who was at the 1968 Democratic National Convention when Lyndon B. Johnson chose not to seek re-election, said Harris gives Democrats a better chance to reach undecided voters.
"Harris, I think, can be a much more effective, articulate spokesperson for what they believe," Stein said.
The Democratic nominee won't be official until the DNC in Chicago which begin on Aug. 19.
