Americans are politically polarized in their views on environmental protection, and scholars have identified structural and cultural drivers of this polarity. Missing from these theories is a consideration of the emotional dynamics at play in environmentally relevant interactions between liberals and conservatives. Based on analyses of in-depth interviews conducted with 63 politically and socioeconomically diverse residents of four communities in Washington State, we find evidence of important common ground across the political spectrum. Our participants voice support and respect for environmental protection and convey a shared image of an ideal environmentalist: a conscious, caring, and committed individual who seeks to reduce their personal environmental impact. We see political differences arise when our participants evaluate their own relationship with the environment against this ideal environmentalist. Liberals are more likely to align with or admire the ideal environmentalist and conservatives are more likely to challenge or denigrate the ideal. Emotions and competing claims for moral worth, we suggest, play a role in making these political differences polarizing.
