A little more info on the parties:
TS-LKD (Homeland Union - Lithuanian Christian Democrats): descendants of the old Sąjūdis nationalist movement, today basically a mainstream centre-right party, economically liberal but socon and still kinda nationalist.
DP (Labour Party): stands for vague populist bullsh*t, founded by Viktor Uspaskich, a rather shady Russian-born self-made millionaire.
LVŽS (Lithuanian Farmers and Greens Union): stands for vague populist bullsh*t, founded by Ramūnas Karbauskis, a slightly less shady and very much Lithuanian-born self-made millionaire.
LSDP (Lithuanian Social Democratic Party): used to be a party of unideological populist grifters that slowly transitioned into a kinda-sorta principled centre-left party.
LSDDP (Lithuanian Social Democratic Labour Party): LSDP members unhappy with the above transition, basically.
LP (Freedom Party): a split from the latter as mentioned earlier, founded by a former LRLS leader, rather openly liberal on social issues (quite a thing in a what's still a very conservative country, but there seems to be a market for it, so that's good).
LRLS (Liberal Movement): also a 'liberal' party, but clearly to the right of the former. Has a former leader investigated for corruption, so there's that.
LLRA-KŠS (Electoral Action of Poles in Lithuania – Christian Families Alliance): a party of the 5-6% Polish minority, unabashedly Bible-thumping and really really socon, the pro-Rusianness is because of their connections to the Russian minority, which is tiny unlike in other Baltic countries, but it's still really weird.
CP-T (Centre Party - Nationalists): led by a former TS-LKD guy, vague populists (now that's a repeating theme, isn't it?) who ocassionally make some nationalistic or economically leftish noises.
NS (National Association): conservative nationalists led by Vytautas Radžvilas, a philosophy professor and poor man's Jordan Peterson (after he had his courses cut, he accused the university of being a training place for "employees who serve the neoliberal system").
LŽS (Lithuanian Green Party): more genuine than LVŽS (hard not to be tbh).
LT (Freedom and Justice): basically the same as LRLS sans the corruption part, took their current name after a merger with a one-man party of a former MP for the nationalist Order and Justice (?!) (fwiw, Order and Justice used to call themselves Liberal Democratic Party, though very much in the Zhirinovsky sense).
A honorable mention to the Putin fanboys and fangirls of LLK (Lithuanian People's Party) and DK (The Way of Courage), an almost-dead anti-corruption party that aimed to uncover the vast pedophile conspiracy among the rich and powerful of Lithuania or something.
Worth to mention that recently Valdemar Tomasevski, leader of LLRA mentioned in TV that they are not Polish-interest party and minority interest are not their top priority. And he is obviously right but not probably intentionally - because they are obviously local government clique with shady interests and not a normal party.
There were also Poles taking part in the elections from different lists - most notably from LSDP and LP.
