A quick news item from Texas. Last week, both the Libertarian Party of Texas and the Green Party of Texas made use of approval voting at their state conventions. The Libertarians used it to vote for their US Senate candidate, while the Greens voted to use approval voting in all internal elections, both for officers and for candidate selection, and including requiring its use by county-level parties (no link available yet, but I will update this story if I get one.) These state-level minor parties join the Libertarian Party of Colorado in the use of approval voting, which they first endorsed in 2010.
This is a great step forward for voting reform advocacy. Every large group of people is hesitant to be the first to try out a new idea, but these brave steps—start with the primaries!—will, I suspect, continue to provide evidence for the effectiveness of better voting methods. I'm especially excited by the Green Party of Texas move, as many state-level Green parties (particularly California's) have advocated for instant runoff voting, which would not be nearly as effective as approval voting in helping minor parties get elected.
