Maybe it's just an immutable law of nature that there must be a special session every year that Rick Perry is Governor. I don't see him having a whole lot of enthusiasm for this, however.
The scuttlebutt in the Capitol hallways is that members of the Legislature are talking about wanting a special session for transportation. The idea is that if they are going to severely restrict the Texas Department of Transportation's ability to raise money through toll roads, they'd better find other revenue for roads. And if they're going to do that, and if it involves raising taxes, better to do it in a single-issue environment where the public could be made to understand their decisions.
One possibility being floated: a constitutional amendment on the gas tax issue. Right now, the Texas Constitution requires that 25 percent of gas taxes go to public education. The public might be asked to waive that requirement, either on the full 20 cents in place right now (which would equate to an instant 5-cent increase, but require making up about $750 million a year from other revenue sources for schools) or on the incremental amount raised by indexing the tax to inflation.
