There's no question that Americans are bitterly divided by politics. But in 'Partisans and Partners', Josh Pacewicz finds that our traditional understanding of red/blue, right/left, urban/rural division is too simplistic. Wheels-down in Iowa - that most important of primary states - Pacewicz looks to two cities, one traditionally Democratic, the other traditionally Republican, and finds that younger voters are rejecting older-timers' strict political affiliations. A paradox is emerging - as the dividing lines between America's political parties have sharpened, Americans are at the same time growing distrustful of traditional party politics in favour of becoming apolitical or embracing outside-the-beltway candidates.
