Will Clinton and Obama get pinned down on gun issues during Philadelphia Debate?

I am less optimistic than reporter Linda Douglass:

"When Barack Obama and Hillary Rodham Clinton square off in an April 16 debate in Philadelphia, they may be forced to spend time discussing an issue neither has talked much about in this campaign: gun control," Linda Douglass writes at national journal.com.

"April 16 will mark one year since the murder of 32 students at Virginia Tech, the deadliest shooting rampage in U.S. history.
