Republican Mitch McConnell
, R-Ky., and Democratic challenger Alison Lundergan Grimes
have wasted no time going after each other in the closely-watched Kentucky
Senate race. Grimes has released two video ads and McConnell has released videos of his own while also challenging Grimes to three debates. Both candidates won their respective primaries easily on Tuesday
and are already locked in a neck-and-neck Senate race that could determine the Senate
majority for President Obama
's final two years in office.
