Oregon does save money this way. And they also have a great voter education system. There is an entire voter packet that goes out to registered voters on the candidates and the issues - goes along with the ballot.
The difference between Oregon and Texas policy on voting is that Oregon wants their voters to vote. Texas does not.
Even on the basis of saving money Texas would never go for this. The party in power would never give up their control of elections because they are winning. They kept shooting down affidavit bypass amendments to the photo ID bill, which essentially does a signature match. This is exactly the way mail in ballots work in Texas too. But even though it's good enough for mail in ballots now, voters could not be trusted to sign the oath in person at a polling location. :eyes:
This is an old article but it's a good write up of how it works and the history of Oregon's vote by mail program

How a vote-by-mail experiment transformed the democratic process.(snip)
New Rituals of Democracy
Today, it's hard to see what the fuss was all about. In late April this year, Oregon's 36 counties will mail more than two million ballots for the May 16 primary with little controversy, little expectation of fraud, and a high level of acceptance by the public. A 2003 poll by the University of Oregon showed 81 percent of Oregonians preferred mailing their ballot to going to a polling place.
Other states may struggle with multiple methods of voting, doubts about software, and uncertainty over accuracy and recounts, but Oregon has one system and only one system of casting ballots and it leaves a paper trial. Vote by mail has become a routine part of Oregon's political landscape. But it wasn't easy getting there.
Vote by mail, first of all, is nothing more than an absentee ballot sent to everyone. County elections officers mail out packets about three weeks before Election Day. Voters must return their ballot by mail or drop it off by 8 p.m. on Election Day. State officials say it saves money, increases turnout, and makes voting easier for the elderly, busy parents, or anyone who has trouble getting to the polls. Opponents, though, see increased opportunities for fraud and lament losing the ceremony of going to the neighborhood polling place.
