Senate Democrats are preparing for possible summer action on their still-elusive climate, tax reform and prescription drugs bill, grinding behind the scenes on a new version during high-profile gun safety talks.

With much of Washington’s attention on guns, Majority Leader Chuck Schumer and Sen. Joe Manchin (D-W.Va.) met twice this week on a potential party-line package. There’s more afoot: Schumer and his staff are working with the Senate parliamentarian to help tee up a possible July or August vote. And a prominent Democratic pollster has tested how popular major components of a hypothetical bill would be in Senate battleground states.

The talks could all fall apart, of course, just as they did in December when Manchin rejected a $1.75 trillion, White House-blessed plan. Any bill advanced this summer would be much slimmer than that one, focusing on lowering drug costs, reducing the deficit, raising taxes on the wealthy and boosting energy sources both clean and domestic.

It’s not everything Democrats want, and they may have to take Manchin’s terms in the heat of the midterm campaign season or face another rejection from the mercurial centrist. But with its work deep into the calendar, the party is putting a new spin on an old saying: Build Back Better Late Than Never.
