Today, much like every Tuesday dating back to the dawn of time, brings another round of Democratic primary elections, this time in Kentucky and Oregon. (Hillary Clinton is expected to take the former, while Barack Obama has a slight lead in the latter.) Obama, on track to win a majority of pledged delegates, will spend the evening in Iowa, a symbolic gesture that basically says "this election is over." It's a message with which pretty much everyone but his opponent agrees. For Clinton's part, she offers several reasons she should stay in the race: every single person hasn't voted yet, she's done better in swing states, and, uh, Karl Rove thinks "I am the stronger candidate." Yep. Hillary's won the Rove primary. And she's bragging about it. Onward to Puerto Rico!
