Do a large fraction of legislators reject compromises, even when the compromise moves policy toward their preferred outcome? This chapter uses surveys of state legislators and elected city officials to assess what fraction of officials reject half-loaf compromises that give them some, but not all of what they seek on policy. Nearly a quarter of state legislators say they would reject a proposal that moves the gas tax toward their preferred outcome. Legislators’ rejection of half-loaf compromises exacerbates the difficulties of solving problems in a political environment polarized along ideological lines.
