Fastest growing areas of the US by partisan lean

My interactive map of population changes from 2010-2015 is here:

I think this is the version that treats annexation as population growth.  There is one error - Indianapolis shows no growth due to a technical issue.

There's no partisan data available, but you can probably eyeball it.

Consider this as a request/challenge for mapmakers if this information isn't already easily available.  For curiosity sake, I'm looking for a map that charts where population growth is most prevalent in each state and how partisan those growth areas are relative to the trend of the rest of the state.  (An obvious example being NOVA offsetting Republican trends and population decline in western VA.)  I'm particularly interested in how population shifts in Ohio and South Carolina might affect the political makeup of those states over time.

Thanks in advance.

To add on to the request, I'd love to see this for Southern California. Specifically Orange, Riverside, and San Bernardino counties

The problem with California is that it doesn't have many county subdivisions for which census reported 2015 estimate data.  Unincorporated San Bernadino County, for example, is huge, and either gains or loses population depending on how you treat recent annexations.

The map of percentage gain controlling for annexations is here.

A total population increase map (i.e. numerical, not percentage growth) is here.

Nice maps, cinyc. Thanks!

I originally posted the maps around Memorial Day in the city and town estimates thread here.  Note that I think it was unincorporated Riverside County, California, not San Bernadino, that had the big change from net gain to net loss depending on whether you use the 2010 Actual Census data or 2010 Population Estimates Base as your baseline.  There were remainders of other major counties with that issue, which I detailed in that post.

I also did a diary on RRHElections with maps showing some patterns in cities.  I can't find if I replicated that diary here, like I sometimes do.
