Mapping the Iowa caucus results: how it’s done with R

David Smith writes:

If you’ve been following the presidential primary process here in the US, you’ve probably seen many maps of the results of the Iowa caucuses by now (such as this infamous one from Fox News). But you might be interested to learn how such maps can be made using the R language.

BTW, David includes pointers to Offensive Politics, which self-describes as:

offensive politics uses technology and math to help progressives develop strategy, raise money and target voters to win elections.

A number of interesting projects and data sets that could be used with topic maps.

Other sources of political data, techniques or software?
