Your demagoguery does not hold up to the fact that Democrats recently held a majority in both houses of congress.
Your argument fails to take into account that, due to the filibuster, legislation can be blocked by one party (with no support from the other party) so long as the opposing party doesn't have both a majority in the House and a filibuster-proof supermajority in the Senate.
If it's not such a good idea then perhaps it was only done as a publicity stunt, and that would explain why it hasn't come up again.
I don't know that I care much one way or the other. But saying "Democrats haven't voted it down" is actually different than "Democrats have made it a priority"
But the Dems do get campaign contributions from Oil & Gas companies. Only at 20% of the rate of folks in the GOP but it's not as though it's a 99/1 split.
