Thank you for this comprehensive and informative write-up! 
anti-immigration and anti-migrant discourse has become VERY powerful in this country, so much that even the PSD and PS took it up in this election
That point shows again, that liberals are fascist at heart. Liberal and “left” parties here, that a few years ago had a humane veneer on migration topics, also have adopted right-wing views and are now asking themselves why they lost the support of the left and the right electorate.
If I had to blame 1 single thing though is that the private news channels, where most people get their politics from, are completely dominated by right wing pundits
Yes, absolutely. The same problem since the first communist movements. In bourgeois societies money controls the press/media, combine that with modern attention-economics and we get the conditions for a really popular right wing. I think combating this is one of the keys to redeveloping class-consciousness in western countries, but I have no idea how it can be achieved
Lol, are they complaining that communist are better at capitalism (on an international level) than themselves? Cornering a market and then using it to your own benefit is Capitalism 101
