Senate Minority Leader Mitch McConnell’s, R-Ky., campaign to tie his Democratic opponent, Alison Lundergan Grimes, to President Obama continues apace, the latest example being a campaign ad released Monday underscoring her refusal to say who she voted for in 2012.

Grimes has been approached on numerous occasions and asked point blank whether she voted in 2012 for President Obama, a man who continues to poll extremely poorly in the Bluegrass State.
