Sen. Mitch McConnell's team is not worried about his Democratic opponent Alison Lundergan Grimes demonstrating a slight lead in the latest Bluegrass Poll, which shows Grimes at 46 percent and McConnell at 42 percent.

"We're very comfortable about where this race stands and extremely confident that Senator McConnell will earn the votes of Kentuckians this fall," McConnell campaign spokeswoman Allison Moore told the Washington Examiner. "The contrast between Mitch McConnell's conservative accomplishments for Kentucky and Alison Lundergan Grimes's alliance with President Obama's agenda of Obamacare and the war on coal will become very clear to everyone over the next nine months."
