In the article, "Monica Lewinsky's Contribution to Political Science" John Zaller states the following:

"Even when, as occurred in this case, public opinion is initially responsive to media reports of scandal, the public's concern with actual political achievement reasserts itself. This lesson, which was not nearly so clear before the Lewinsky matter as it is now, not only deepens our understanding of American politics. It also tends, as I argue in the second half of this article, to undermine the importance of one large branch of public opinion research, buttress the importance of another, and point toward some new research questions."

Identify the branches of public opinion research that will be undermined in importance and buttressed in importance, and discuss why Zaller makes these claims.
