Political science vs political journalism, continued

Christopher Beam illustrates the point I was trying to make about political journalism and political science the other day with humor:

A powerful thunderstorm forced President Obama to cancel his Memorial Day speech near Chicago on Monday—an arbitrary event that had no affect on the trajectory of American politics.

Obama now faces some of the most difficult challenges of his young presidency: the ongoing oil spill, the Gaza flotilla disaster, and revelations about possibly inappropriate conversations between the White House and candidates for federal office. But while these narratives may affect fleeting public perceptions, Americans will ultimately judge Obama on the crude economic fundamentals of jobs numbers and GDP.

He goes on. Funny, and accurate.
