Yes. That's the other thing liberal Westerners refuse to understand about Russia. The Western media loves to style pro-Western guys like Garry Kasparov and Alexei Navalny as "Russian Opposition Leader" but those guys never got more than a few percent of the vote in any Russian election. Not even in Russia can you rig a vote that extravagantly, so the lack of support is genuine.

The second biggest political party in Russia is the Communist party, and it has been since the fall of communism. Their perennial candidate is Gennady Zyuganov, who gets between 10-15% of the vote in every presidential election (except the one he didn't run in). If there is a leader of Russia's opposition, it's that guy. There are communist mayors of some major Russian cities, and they have the second biggest number of seats in almost every legislature, national and regional.

The other big opposition party is the Liberal Democracts, who are neither liberal nor democratic. They're the ultranationalist hard-liners you mentioned who are advocating scorched-Earth in Ukraine.
