Voters approved all but one of the 10 proposed amendments to the Texas Constitution in Tuesday’s election.


Only Proposition 1 — a little discussed amendment on municipal judges — limped to defeat after getting support from only 35% of voters. The proposal would have allowed elected municipal judges to serve more than one municipality at a time, something the vast majority of judges, who are appointed, can already do.


A closer race played out on Proposition 9, exempting precious metals from taxation, including metals held in the Texas Bullion Depository, which was supported by 53% of voters.


The most-watched amendment, Proposition 4, which would make it harder to adopt a state income tax, was favored by 76% of voters.


"Today’s passage of Prop 4 is a victory for taxpayers across the Lone Star State," Gov. Greg Abbott said. "This ban on such a disastrous tax will keep our economy prosperous, protect taxpayers and ensure that Texas remains the best state to live, work and raise a family."


Abbott and other supporters said Proposition 4, which would require an income tax proposal to receive support from two-thirds of the Texas House and Senate instead of a simple majority, would protect the state’s status as a low-tax, pro-growth haven while acknowledging strong historic opposition to an income tax.


Opponents called it unnecessary political posturing because state voters would still have to approve an income tax, unchanged from current law. They also said today’s voters should not be deciding policy for future Texans.


"Proposition 4 was completely unnecessary, but more lawmakers wanted to score political points by putting this in front of voters rather than to make serious decisions about funding our future," said Ann Beeson, CEO of the Center for Public Policy Priorities.


With almost all votes counted, other amendments added to the Texas Constitution included:


Proposition 2, letting the Texas Water Development Board issue $200 million in bonds for water supply and wastewater projects for lower income areas in Texas, was supported by 64% of voters.


Proposition 3, providing temporary property tax exemptions for buildings and other property damaged in a disaster, had 85% in favor.


Proposition 5, requiring money raised from the sales tax on sporting goods to be spent on maintaining and improving Texas parks and historic sites, got 88% of the vote.


Proposition 6, adding $3 billion in bonds to let the Cancer Prevention and Research Institute of Texas continue offering research grants for another decade, won with 63% support.


Proposition 7, adding up to $300 million a year for public education by doubling the cap on the Available School Fund — which pays for textbooks and other instructional materials and funds schools on a per-student basis — had 73% support.


Proposition 8, creating the Flood Infrastructure Fund to promote large-scale flood-prevention projects, was favored by 76% of voters. The fund will include $793 million from the state’s rainy day fund.


Proposition 10, letting handlers adopt retired law enforcement dogs and horses, had the highest level of support, with 94% in favor. The animals are currently classified as surplus property, requiring them to be sold instead of adopted.
