We want to make the world better by our lights, and to do that we need a stronger democracy. Patriotism in the right spirit fosters the civic trust and solidarity that democracy needs. A recent Quinnipiac poll asked Americans whether they would fight or flee if the country were invaded: 68 percent of Republicans said they would stay and fight, compared with 40 percent of Democrats. Although such questions can only be conjectural, this one does suggest that some progressives are not so sure the country is worth saving, or at least risking their lives to save.Conservatives often say that liberals don’t really like this country, and these figures suggest they might have a point. In progressive circles, claiming patriotism is, at best, an eyebrow-raiser. But progressives need patriotism, more than ever in a time of understandable anger and despair.
