Explain Ukrainian politics to me

[Famous Mortimer]

Radical Party is primarily anti-Russian.
Patriotic Front is differentiated from the Poroshenko Bloc by also being more hawkish towards Russia.
Poroshenko Bloc is generally pro-Western but much more willing to compromise than either the Radical party or the Patriotic Front, as Poroshenko is an oligarch with ties to East and West.
Fatherland/Tymoshenko is a wild card. Now it's publicly anti-Russia but unlike the others it has the potential to switch sides, Tymoshenko has a good relationship with Putin and the reason she was in jail is because she gave him a too sweet deal on gas.

Wasn't Mikheil Saakashvili (lol) starting his own party?

He got chased out of Ukraine for being terrible and lives in Brooklyn now.

Also, I've never heard the Freedom Party being characterized as left-wing on economics before. I know this is common with a lot of far right parties throughout Europe but I just never heard it with them. In general, Western Ukrainian politicians generally are pretty free market and Eastern Ukrainians more left-wing. Easterners are more likely to be explicit about their economic policies while Westerners usually just hide behind Ukrainian nationalism or anti-Russiaism because obviously free market capitalism isn't super popular in Eastern Europe in general.

Orange parties are definitely more free market. Both Poroshenko Bloc and Fatherland are in the European People's Party. People's Front isn't but Arseniy Yatsenyuk is even more explicitly neo-liberal than either either Poroshenko or Tymoshenko. Our Ukraine, when it existed, was a big tent party but almost everyone in the tent was pro-market.
