AUSTIN, Texas -- The top two candidates for Texas Governor squared off in their first and only debate Friday night in Austin. Republican incumbent Gov. Greg Abbott defended his first term while largely ignoring his Democratic challenger Lupe Valdez. 

Valdez worked to portray Abbott as unwilling to adequately fund public education and criticized him for not calling a special session to tap the state's Rainy Day Fund after Hurricane Harvey.

"He calls a special session for bathrooms but does not call a special session when people are dying," Valdez said referring to the controversial "bathroom bill" from last session. 

Abbott responded that the Governor has the authority to spend state money without calling a special session. He repeated previous comments that that money will be repaid from the fund once the legislature meets in 2019. 

The two also showed stark differences over immigration and guns. Abbott reiterated his support for arming teachers or other school personnel in the aftermath of the deadly Santa Fe High School shooting. Valdez said that's not teachers' job and that they're already overworked and underpaid. 

Valdez supported maintaining in-state tuition to some undocumented immigrants through the 2001 Texas DREAM Act. Abbott called it a noble, but flawed idea and claimed it doesn't ensure recipients are working toward legal status. 

The two did find some common ground. Both said they were in favor of moving toward marijuana decriminalization. 

"I would be open to talking to the Legislature about reducing the penalty for possession of two ounces or less from the Class B misdemeanor to a Class C misdemeanor," Abbott said. 

"We agree on something," Valdez chimed in. 

The hourlong debate was at the LBJ Library. Libertarian Mark Tippetts is also on the ballot but was not included in Friday's debate.
