Wow, a country with a ruling party whose strongest support group is young people. Compared to a lot of other countries, I'd say there's hope for Poland.
The left? Lots of scandals which they tried to deny/cover. Lost trust, their new leader perceived as sleazy. The "right"? They cater to religious old people and their fears of change. PSL? Farmers' & big food interests. Palikot? He is the one catering to the young (reduce influence of the church, legalize MJ) but IMHO he's trying too hard to be perceived as trustworthy.
