11. Nothing new

At least as far back as the 1928 presidential campaign, Republicans have painted big cities, and those that come from them (as Al Smith was a New York Irish Catholic at a time when all three were seen as "alien" to much of the US), as things to avoid. It's a big part of the reason Hoover crushed Al Smith, though he'd likely have won a narrower race regardless.
