The table reports coefficients of a linear probability model. Robust standard errors in parentheses, adjusted for clustering at the state level in columns 1–4 and senator level in columns 5–7. The dependent variable Voteijvt is coded as 1 when senator i from state j voted pro-environment on vote v in year t. All specifications include senator controls. The sample covers the period 1971–2012. The last row reports the p-value of the test. ***, ** and * indicate statistical significance at 1%, 5%, and 10%.
