Political scientists frequently moan about the reluctance of political journalists to read their work and use it when making horse-race prognostications. So it’s nice to see Tom Edsall (previously at the _Washington Post_, now at HuffPo) do a “long piece”:http://www.huffingtonpost.com/2008/06/24/obama-rides-the-wave_n_108848.html on the implications of recent work on political cycles for the upcoming election. As a non-Americanist, I’m not very well grounded in this literature (my broad impression is that it’s a bit skimpy on the causal mechanisms), but even so.
