Speaking directly to Republican Senator Mitch McConnell, Democratic candidate Alison Lundergan Grimes says she plans to hold the GOP accountable in next year's election.
In a nearly four minute kick-off ad, Grimes says she doesn't always agree with President Obama, but that McConnell is blocking legislation that would've helped Kentuckians out of spite.
"Your campaign wants to play silly games about where I am and where I stand. Well I'm right here in Kentucky senator, where I'll be holding you accountable," says Grimes to McConnell.
"We'll have this debate senator, and as you've probably already seen, I don't scare easy."
The video also uses a clip from her successful secretary of state bid in 2011, which was praised by observers for its humorous tone and featured Grimes's two grandmothers.
Grimes's paternal grandmother, Thelma, died a few months after the ad first appeared and the Democratic challenger cites her as one of the chief reasons for running.
"Grandmother knew that if you wanted to get something done, you don’t stand in the way," says Grimes. "You stand by your principles, but you also figure out where you can agree and how we can come together. But that's not happening in Washington today, and Senator McConnell is the biggest part of the problem."
