I looked it up, and the population of Miami (the city itself, not the metro area, thus comparing apples to apples with Cincinnati) was 362,470 in 2000 and 399,457 in 2010. I also confirmed that at all times since the 2002 elections there have been three Cuban-American Republican Congressmen who resided in Miami (Lincoln and Mario Díaz-Balart and Ileana Ros-Lehtinen from 2003 to 2011 and Mario Díaz-Balart, Ileana Ros-Lehtinen and David Rivera since 2011). And I was surprised to learn that Kendrick Meek is listed as a resident of Miami, and that his successor in Congress, Frederica Wilson, is listed as either a resident of Miami or Miami Gardens depending on where you look. So from 2003-2011 Miami had four congressmen despite having a population of below 400,000!
Well, the difference between Miami and Cincinnati is that because of the VRA requirements for the former, you have all those crazy lines criss-crossing everywhere. Unlike Miami, Cincy has had deteriorating to stagnant growth over the past several decades, hence my comment that for a city (not under the VRA requirements) of less than 300k having two city-based members is unusual. I’m rather surprised the urban-based Wenstrup was able to win when you consider Schmidt hailed from the suburban section of the district (I’ve not seen the new lines, so I don’t know how much of urban Cincy is in the redrawn 2nd). Of course, when Cincy was a much larger city of over 500k, it used to have 2 members entirely within the city boundaries.
