On which side of a dais should the American flag be placed? (Hint - Don't ask Robin Carnahan)

The correct answer is . . . to the right of the speaker in the "position of honor."  (Link to relevant U.S. Code section here.)

It seems that U.S. Senate candidate Robin Carnahan, shown above in a shot taken from a video that her campaign posted on the web, is unaware of this protocol.

Here's a small bit of advise, not given to help your candidacy, but to ensure proper respect for the flag . . . please make yourself aware of the rules for proper display of the flag.
