Yes because polls are even easier to rig than elections. This way, Dems can deny reality even longer and claim their ideas and values were never actually rejected by the voters.
And it concerns me that this is the strategy of the "Big Lie" being told over and over, year after year. The lie being that we don't have free elections in this country, that so-called impartial polls show that voters prefer Democrats, and that obviously Republicans have stolen elections to stay in power. That's the big lie that Democrats want to tell the American people.
