After a recent poll showed him trailing Rand Paul by 15 points, Trey Grayson is up with a new ad and website calling into question Paul's "strange ideas."

It's more of the same from Grayson's campaign, which has now run three ads featuring Grayson in front of a white background calling into question Paul's positions.

Interestingly, if you add an 's' after Rand Paul in that web address, it links to Paul's campaign website.

UPDATE: Paul's campaign has another quick response.

A distinct pattern is developing here: Grayson tries to marginalize Paul, and Paul fights back by tying him to President Obama.
