Conservatives have long dreamed of passing a bill to shred tons of regulations. They may be closer than ever.

Conservative Republicans have spent more than a decade working toward a wholesale rollback of federal regulations — and now they think they have the legislative battle plan to make it happen.

Advocates of the rule-shredding proposal are seeking to give their legislation a coveted spot in the GOP’s party-line energy, tax and border security megabill, a maneuver that would defuse the filibuster threat that has repeatedly thwarted their dreams. They say they have spent the better part of the past year crafting ways to ensure their latest iteration can pass muster in the Senate.
