However, there are a few Democrats who have voted against NN in the past, or have indicated that they do not support it.
From this vote in 2016: http://clerk.house.gov/evs/2016/roll152.xml
You have:
Jim Costa (CA-16)
Scott Peters (CA-52)
Collin Peterson (MN-07)
Kyrsten Sinema (AZ-09)
Albio Sires (NJ-08)
If you live in their districts, call up their office and tell them that you want them to change their tune on NN. Go to their town halls and tell them there.
There are also four Democratic Senators who listed as being part of 'Team Cable' according to this: https://www.fightforthefuture.org/news/2017-10-04-democrats-...
Again, if you live in their states (MI, MO, MT, or WV) call them up and tell their staffers that you want them to change their mind on NN and tell them why. Go to their town halls and tell them there.
Bemoaning your elected officials' choices without ever trying to influence them will not change anything.
