That is true, but I don't see democrats as much better. I see Political literacy as reflected in the pervasiveness and power of grassroot political movements. Something of which America has very little, or if they do exist, get quickly crushed and whitewashed by the politically illiterate (for example, BLM had lots of potential, but was desensitized into nonexistence).
As well, Literacy in general should also be political literacy, since life and politics are inherently intertwined. Education is what has given us average folks the ability to do what was previously impossible, and move the world in ways that weren't ever before imagined. An illiterate population is a manipulated population.
