This map is possible, but about Pollsters solving problems from past... They also said it in Portugal about Azores 2020, after falling 2016 by big margin like you can see here.
In 2020 mistake wasnt so big, but existed, even after pollsters guaranting that was much less probable than in 2016, PS had 5.4 lead instead of 13 lead, all right parties had better results than predicted (PSD, CDS, PPM, Chega, except IL that had +- the same). PSD now is centrist, but is considered as Right here. This only happened because turnout altought.
