Manchin's surprise change of heart could impact internal Democratic caucus politics.
Driving the news: West Virginia Democrat Joe Manchin unexpectedly opposed Bernard McNamee in a procedural vote yesterday, citing his early 2017 comments recently unearthed by the publication Utility Dive.
Why it matters: The change of heart arrives as some progressive activists are pressing Democratic leaders to block Manchin from becoming the ranking Democrat on the Energy and Natural Resources Committee.
The big question: Whether yesterday's surprise move will affect the internal Democratic caucus politics around Manchin's potential ascension on the committee.
Yes, but: Don't look for activists to end their campaign against Manchin.
What's next: McNamee, meanwhile, is still expected to win approval along party lines today after surviving yesterday's 50–49 procedural vote.
