“…A look in the literature makes clear that issues taking this form are seen as rather influential as it has been shown that performance effects are usually stronger than position effects and retrospective evaluations have more weight than prospective ones (see, for example, Wattenberg, 1995;Kra¨mer and Rattinger, 1997;Nagler, 1998, 1995;Clarke et al, 2004;Veiga and Veiga, 2004;Aardal and Wijnen, 2005;Listhaug, 2005;Whiteley et al, 2005, but see also MacKuen et al, 1992;MacKuen et al, 1996;Norpoth, 1996). Political psychology literature teaches us further that only highly salient attitudes have an effect on behavior (see, for example, Fazio, 1986Fazio, , 1989Aldrich et al, 1989), therefore we expect the issue of social policy to be influential particularly for people rating the topic highly important.…”
