What issue has this nation ever faced that had no partisan divide? That's normal politics.
This one is not currently a partisan divide, but maybe it could be made into one - the proper pronunciation of gerrymander is “gary”mander.
The portmanteau was created in a political cartoon showing Vice President Elbridge Gerry’s redrawn Massachusetts district as a medieval salamander. The Gerry family, to this day, says its name with a hard ‘g’.
Gerry, curiously enough, was a nonpartisan politico (by today’s party descriptions), being a Democratic-Republican.
