From JFK to Trump, Irish American voters have played a pivotal role in US politics, but is their influence on the wane? The Tribe provides a definitive, clear-eyed look at Irish American voters. Caitriona Perry explores the role of Irish Americans in the US political system. Once considered to be kingmakers in local and national elections, generations of assimilation and rising numbers of newer immigrants have diluted their power and influence. Leading Republicans and Democrats, including Senators, Congressmen and women, and Vice Presidents, explain that they no longer target a notional `Irish voting bloc', that the concept has long faded. Many proud Irish American Republicans lay out why they align more with conservative ideals, despite the beliefs of some of their relations in Ireland that all Irish in America are Democrats. Caitriona also meets many of President Trump's Green Army, who are Red and Green and Proud.
