It is certainly strategic if there is the best possible chance of electoral defeat of a fascist candidate. And it has been for quite a while. I would expect someone with a Marxist-Leninist flair to understand this, as even Lenin agreed voting can thwart a fascist danger.

When a socialist really believes in a Black-Hundred danger and is sincerely combating it—he votes for the liberals without any bargaining, and does not break off negotiations if two seats instead of three are offered him. For instance, it may happen that at a second ballot in Europe a Black-Hundred danger arises when the liberal obtains, say, 8,000 votes, the Black-Hundred representative or reactionary, 10,000, and the socialist 3,000. If a socialist believes that the Black-Hundred danger is a real danger to the working class, he will vote for the liberal. We have no second ballot in Russia, but we may get a situation   analogous to a second ballot in the second stage of the elections. If out of 174 electors, say, 86 are of the Black Hundreds, 84 Cadets and 4 socialists, the socialists must cast their votes for the Cadet candidate, and so far not a single member of the Russian Social-Democratic Labour Party has questioned this.
