Nice profile of State Sen. Rodney Ellis, which talks about his propensity for introducing long-shot bills, and his persistence in getting some of them passed over the course of multiple sessions. This bit summarizes it well:
"Occasionally, Senator Ellis will pick an issue whose time has not yet come, but that's the legislative process, in that sometimes it takes a little time so we can get a consensus and a majority," said Lt. Gov. David Dewhurst, a Republican, who calls Ellis one of the state's "brightest, most charismatic senators."
