That's completely untrue. You seem to misunderstand the entire issue.
Imagine 3 districts in an area split 55-45 Dem to Rep. If you draw the
lines so that 2 districts are (D to R) 40-60 splits, that leaves the other at
85-15, you
guarantee two Republican representatives and one Democrat. If everything were
evenly split-up, then there would be 3 Democrats. Gerrymandering COMPLETELY
undoes the democratic system. It's a primary issue in our system and 100%
voting turn-out would do NOTHING to stop it.
The extra 42% of voters are voting within lines already drawn. So the lines will continue to achieve their effect and keep the people who drew them in power.
