Are S&D parties becoming unelectable?

[Mike88]

Opinion polling for next parliamentary election (S&D members):
1st place: Denmark, Lithuania, Malta, Portugal, Romania, Slovakia**, Sweden
2nd place: Belgium, Croatia, Italy, Luxembourg, Slovakia**, Spain
close 3rd place: Austria, Finland, Germany, Latvia
minor party/parties: Bulgaria, Cyprus, Czechia, Estonia, France, Greece, Hungary, Ireland, Netherlands, Poland, Slovenia

*incumbent government leader - bold
** two S&D members are 1st and 2nd in polls

Though in Portugal the PS will be second soon if they aren't already - whilst in contrast the PvdA seem to be making a bit of a comeback (they've been up and down like a yo-yo in recent years)

In Portugal, the PS is second depending on the polling firm but almost always up or behind by just 1%, which is nothing more than a tie. However, not sure if the trend will continue, as political events are being very volatile.

But one must expect the broader trend of the PS regime being unpopular will carry on for a while.

Being unpopular yes, but if that means more support for the main opposition party, I'm not sure about that.
