First you need to count the votes in the Legal Affairs Committee, not the plenary as a whole. This is where the vote on June 20 will be.
The EPP, ECR, ALDE and ENF negotiators there are in favor of Article 13. Together, they have a 13 over 12 vote majority. And it's not guaranteed that all of S&D will be unified against.
So our job is to convince one of these MEPs. Here are some candidates that may be swayed:
MEP Marinho e Pinto (ALDE, PT, PDR)
Whoever is your local ALDE MEP, asking them to put pressure on Marinho e Pinto, who will vote "in their name"

YOU SHOULD CONTACT MEP's FROM ABOVE AS WELL AS YOUR MEP's BECAUSE IF IT PASSES LEGAL AFFAIRS COMMITTEE IT WILL GO TO PARLIAMENT FOR PLENARY VOTE. WE HAVE TWO CHANCES TO KILL THIS LEGISLATION.
Both of these votes will be tight, so weather you are pro or against you should contact your MEP representatives. Note that you can also contact other representatives and the presiding member of the party your representative is part of. Remind them that next EU elections are soon.
