Poland has two main parties and several smaller, but still politically-meaningful parties.
The two main parties are like the two wings of the U.S. Republican Party. I realize that on this site there are MAGA Americans who dislike moderate Republicans even more than they dislike the leftists in the Democratic Party. And, there are Putinbots who are looking to sow discord in the west. But, having the country’s two major parties be to the right of the center of American politics is a good thing.
Your characterizations are somewhat correct
PiS - Big government, socially conservative (actually more that it uses this cynically), patriotic (more in word than actions), financially left/socialist/welfare
PO - Mid-sized government, socially liberal (actually more that it uses this cynically), not patriotic, financially rightISH/socialist/welfare
Lewica - LEFT - ex-Communists. Socially highly liberal. And, well, communists
Trzecia Droga - Mid-sized gov, socially conservative-ISH, patriotic-ISH, finanicially socialist
Konfederacja - Small gov, socially conservative, patriotic, financially right.
Eh?
