Fake poll with fake results.
Without knowing the internals or specifics of the poll, my first reaction was that this is part of a movement to "normalize" the acceptance of socialism.
Because there is a movement afoot today to do just that. The Communists (Socialists are Communists who simply don't know it yet) are like Marx, who thought the time was ripe for a revolution 1848, encouraged the people to throw off their chains and take power.
He (and they) failed.
I believe today, these scum are coming out of the woodwork in our society and politics because they believe the time is right for Communism to rise as it did in 1918 in Russia.
It did cross my mind that this is simply a part of the propaganda campaign that encompasses Media, Entertainment, Education, and Government.
