And after looking up everything but the TX and FL cities, I just realize that all of these are such places and you're not interested in the figures but the reasons. Oopsie...
Yes, I listed cities that fit the topic line, though using Lephead's tables (though DRA may be may accurate), I don't find the figures for the following cities:
Albuquerque NM Bernalillo
Precinct design is wacky, and so is the DRA for the state (a comma error of some sort) but as far as I can make out there's virtually no difference in election outcome between the sixth of Bernalillo outside the city limits and the remainder. Though the parts outside are three points or so less Anglo.
Charleston SC Charleston, BerkeleyThis
sort of thing
probably explains why Lephead has no figures. However, unless the unannexed people in West Ashley and John's Island and James' Island are much more Democratic than the annexed people, Charleston city is more Democratic than Charleston County - 54.5% Obama for all of the Peninsula, West Ashley / St Andrews, the two islands, and the partially annexed areas in Berkeley County. The Peninsula itself - the historic city of Charleston as it was until I think the 1990s - is 74% Obama but also just not very large. North Charleston, ie the mainland bits north of the peninsula and still outside the city, is 70% Obama, but the Whites in Mount Pleasant and the far suburban bits to the west more than even it out.
Lakewood CO Jefferson
Aurora CO Arapahoe, Adams
Thornton CO Adams
Westminster CO Adams, Jefferson
While there are cases of precinct design not aligning with city boundaries in Colorado as well, the issues are minor and the following figures are as accurate as can be produced:
Lakewood 57.9% Obama
Aurora 62.5% Obama
Westminster 57.2% Obama
Thornton 57.8% Obama. Which makes Thornton marginally less democratic than Adams County as a whole. Of course, all these are suburbs really, not cities.
Abilene TX Taylor, Jones
Denton TX Denton
Plano TX Collin, Denton
Round Rock TX Williamson
Worse issues than in Colorado, not as bad as in Charleston - differing very much from city to city with Round Rock being bizarre and Plano being as near to a perfect match as makes no difference.
Abilene is app. 70.8% McCain - ten points less than the remainder of the county.
Round Rock is very approximately 51.8% McCain. It's a suburb, of course - Georgetown is the older urban center in Williamson County - but it is a suburb of Austin
Plano is 59.8% McCain. It's a large splosh of random suburbia, not a city, but it's on the southern side of Collin County. (The bit in Denton is one precinct.)
the older urban core in Denton County, and is also a not so tiny college town, but has city limits that extend beyond the urban core into exurban sprawl. It also has a rather bad match between precinct lines and city lines, but I'd approximate it at having given John McCain 51.2% of the vote. You can pretty much split it into an l-shaped southern and eastern, plus a bit on the other sides, half that voted 60% McCain and a center-with-bits-to-the-north-and-west half that voted 60% Obama.
