The two far-right parties in Portugal, the Iniciativa Liberal (American-style ultra-neoliberals) and the Chega (Fascists) were the only parties who grew their vote and Parliamentary representation, which together now adds to almost 20%
Further, if you add them to the AD cohalition (containing the center-right party and the traditionalist conservative one) who came second just a short way from the first placed, and even if you consider the winner a leftwing party (whilst they're supposedly center-left, their politics are "slightly socially-aware neoliberal", so them being left-of-center is open to dispute), AD plus the two far right parties still adds to a victory of the Right when last time around it was the Left that was ahead.
There is no way in Hell any of this shit can be seen as a victory from the point of view of the Leftwing unless "we didn't got trashed as much as we could" is a "victory".
