Already voted for this European election (vote by letter)
The conservatives and Social Demcrats should remain the biggest parties. However, Eurosceptics could become the third power an wreak havok from within.
Apart from the Eurosceptics and the Liberals, I see a rise for more leftist and green parties. So, United Left - Nordic green Left (GUE-NGL), Green - European Free Alliance (Greens-EFA), and possibly the Party of the European Left may get a rising number of votes
Not sure about the eurosceptics. Seems like the EFFD and ENF will be dumped in favor of going together as EAPN and it seems the Brexit party is pretty successful in the UK. So this all makes it a bit complicated. In some projections I see Greens win stronger, in others only a few seats, so I didn't talk about them. But it seems Greens win big in Germany. GUE-NGL seem to lose even some seats.
I thought the EAPN was seperate to the other two, so I added those votes together. If that ain't the case, my bad.
And yes, GUE-NGL looks like it will be stable or loosing seats. If it does, I expect those to go to PEL instead, keeping a light movement to the left in general for the European election.
