The Senate easily approved a bipartisan public lands package Wednesday by a 73-25 vote in what Republican supporters see as a major conservation achievement that will aid vulnerable members in the upcoming election.

Senate Majority Leader Mitch McConnell and the bill’s main Republican sponsors, Sens. Cory Gardner of Colorado and Steve Daines of Montana (both in tight reelection fights), blocked debate on amendments in the lead-up to the vote to ensure passage.
