The coalition is a mix of left (Lewica), center (Donald Tusk's KO) and center-right (PSL).

KO generally voted against the ban, it was PSL who voted overwhelmingly against it, which, together with PIS, made it so that the ban was upheld.

There's good reasons to hate Tusk, and I share a lot of them, but this one isn't it. With the cards he was dealt, there wasn't much he could've done.
