When men are arrested without any legal basis and for political reasons, it's merely a routine, everyday occurrence in Russia, and hardly anyone has any sympathy.

Putin needs to terrorize his own elite. He is more afraid of those in his own surroundings than any protests; there are people there who are at least as critical as I am because they see up close that the system doesn't work. He wants to silence them.

I've always seen my campaigns against corruption as political work of a purer form than what opposition leaders usually do. All they do is hold roundtables and release political statements, which is all well and good. But there are concrete things that need to get done in order to achieve the basic goal of every opposition politician.

Russia should join the international coalition against Islamic State. It is absurd that we are intervening on the side of the Shiites in a war between Sunnis and Shiites even though almost all Russian Muslims are Sunnis. Putin is creating big problems for us in his attempt to help Bashar Assad.

As far as I know, the people who are against my candidacy now have the upper hand in the Kremlin. They say: Who knows what the election result will be? We already made that mistake once. And they are also afraid of all the things I would say if they let me run.

I don't know why, but Putin has made a ritual out of humiliating Medvedev. Sometimes I even feel sorry for the prime minister.

I'm only sort of a politician.
