Nearly three months after they swept in, House Republicans are almost ready to take the first big piece of their agenda to the floor. And it’s not exactly a shoo-in.

Speaker Kevin McCarthy and his team have spent weeks assembling a marquee energy package designed to unite their fractious conference and accomplish one of their biggest pledges from last year’s gas-price-obsessed midterms. The energy package — which they aim to pass the last week of March — is set to include some of the party’s most popular pitches over the past decade, from boosting fossil-fuel production on federal lands to disapproving of President Joe Biden’s block on the Keystone XL pipeline to easing environmental reviews of energy and mining projects.

But that wide-ranging appeal across the GOP’s ideological spectrum also creates more pressure points for McCarthy to manage. He’ll have zero room for error and face a herculean task in preventing last-minute changes on the floor that could risk unraveling the entire plan.

“Everybody will have a little different perspective. But when you want to attack inflation in this country, it starts with an all-of-the-above energy policy, and I think that will be the more unifying thing,” said House Majority Whip Tom Emmer (R-Minn.).

Miles of unused pipe, prepared for the proposed Keystone XL pipeline, sit in a lot on October 14, 2014 outside Gascoyne, North Dakota.
