Kentucky Secretary of State Alison Lundergan Grimes (D) is hitting the airwaves with her first general election TV ad, a minute-long spot in which she casts herself as candidate not beholden to either her party or the president.

"I believe that we need a senator who puts partisanship aside and works with both Democrats and Republicans to do what's right for Kentucky and for our country," says Grimes. "And no matter who the president is, I won't answer to them. I'll only answer to you."

Grimes does not mention she is a Democrat in the ad. The commercial will air statewide and is backed by a six-figure buy, Grimes's campaign said.

Republicans have been working to tie her to national party figures. A group backing Grimes's opponent, Senate Minority Leader Mitch McConnell (R), this week released a commercial that seeks to tie Grimes to President Obama, who is very unpopular in Kentucky.

On Tuesday, both McConnell and Grimes easily won their primaries.
