I'm guessing it will have better luck under the current congress and administration than the last one.
And to be honest, I think all these shale plays (and the jobs, etc. they bring) have probably become enough of an enticement to more congressmen (and women) to promote NGV's because they realize increased use of NG will set forth a drilling boom in their districts and states, and create more jobs and so on. These things have become big enough that they're as much of an economic development tool as an energy-producing tool.
Look for senators and congressmen from OK (already there), PA, WV, LA, TX and maybe even upstate NY to be big supporters of this.
