Well, the thing is the Politburo was a Bolshevik party organ used to overthrow the government. Party as opposed to state in other words. And even it gives us a Politburo of a little over 70% if we count Lenin and Kamenev. Putin spoke of 80-85% which does not correspond to the politburo, the central committee of the party, or the state council of people's commissars. That means he was likely referring to Wilton and Shuyler - the standard go to guys for Judeo-obsessives like David Duke. Obviously they are contradicted by what we have seen on this thread:

The London Times correspondent in Russia, Robert Wilton, reported: ”Taken according to numbers of population, the Jews represented one in ten; among the commissars that rule Bolshevik Russia they are nine in ten; if anything the proportion of Jews is still greater.”

On June 9, 1919 Captain Montgomery Shuyler of the American Expeditionary Forces telegrammed from Vladivostok on the makeup of the presiding Soviet government: “… (T)here were 384 ‘commissars’ including 2 negroes, 13 Russians, 15 Chinamen, 22 Armenians, and more than 300 Jews. Of the latter number, 264 had come to Russia from the United States since the downfall of the Imperial Government."
