HOUSTON -

The first Election Day in Texas under a new photo ID law was being as closely watched for how voters fare under the mandate.

State officials say turnout was high as Texas voted Tuesday on nine proposed constitutional amendments. Getting the most attention is a widely supported $2 billion plan to accelerate new water projects statewide.

In the Houston area, major issues on the ballot include the race for Houston’s next mayor, the fate of the Astrodome and a bond package that includes $69.5 million for a new, 14,000-seat football stadium in Katy.

The off-year election wouldn't be distinctive if it wasn't for the enforcement of the voter ID law. There's little drama on the ballot.

Republican Attorney General Greg Abbott says a nearly twofold increase in early voting from 2011 shows the photo ID law isn't causing problems.

Democrats and opponents of the law say the potential for confusion, turned-away voters and disenfranchisement is real.
