Political parties shape public opinion, but their influence is limited

Do people’s opinions on policy debates follow those of the political party they support? In new research using a nationally representative survey, Kevin J. Mullinix finds that knowing that their party supports certain legislation means that people are more likely to support that legislation, and that this effect is more pronounced when parties are highly polarized. This effect is not absolute, however; when an issue is personally important, people will not blindly follow their party’s lead.
