From the five-day rollout of the University of Texas/Texas Tribune Poll: Rick Perry would beat Greg Abbott 3-1 in a Republican primary for governor held today; Texans don’t want a lot of new gun laws but would overwhelmingly support mental health and criminal background checks on all gun sales; the federal government is on the wrong track and immigration and border security top state problem lists; Texans’ position on abortion isn’t changed, but they would support a “fetal pain” ban on abortions after 20 weeks; a surcharge based on water use beats a tap fee as a way to finance infrastructure projects; and Republicans and Democrats utterly disagree on whether Texas should have to get federal permission to change its election laws under the Voting Rights Act.
