I think Greg has three-peated on his bet with Jay Mathews regarding school choice expansion. Here is my count, with a few of these not being totally done deals yet (but close enough):
Alabama new tax credit program
Arizona ESA expansion
Indiana voucher program expansion
Indiana tax credit program expansion
Iowa tax credit expansion
South Carolina new tax credit program
Utah voucher program funding increase and formula funding
Wisconsin voucher program expansion
New program discussions are still ongoing in North Carolina and Ohio. Even before knowing how these turn out, 2013 already represents a very solid year for the movement with two new states added to the choice family and some significant improvements to existing programs.
UPDATE: Paul Diperna wrote me to note that Alabama passed both a refundable and a scholarship credit- meaning two new programs. Extra style points for Greg.

Looks like Ohio is a done deal – http://www.edchoice.org/Newsroom/News/Ohio-House–Senate-approve-vouchers-for-low-income-students.aspx
Also, Arizona expanded its scholarship tax credit program as well (at least it expanded the types of donors who can participate in the corporate program, which will mean more funding, particularly with the escalator).

I think that bill received a veto, although the Governor’s veto message said that she hoped to work on language for next session to get it through..
Ugh, really? I wrote about it after it passed the House. I forgot that we have an unpredictable lunatic for governor.
