And as for why it happened, I'm no expert on the Texas procedures, but what my friends there tell me is that the governor opposed a measure put forward by Democrats in the legislature to expand the number of children that would be covered. And instead directed the money toward a tax cut, a significant part of which went to wealthy interests.
The democrats measure had bi-partisan support.
