Senate Republican Leader Mitch McConnell has banked another $2.26 million since April, pushing his overall fundraising total to more than $15 million for the election cycle.
Campaign manager Jesse Benton said those totals, which will be reported to the Federal Election Commission on Friday, put McConnell "well ahead" of the fundraising pace of his 2008 re-election bid when he spent some $20 million.
Benton said the FEC report will show McConnell still has $9.6 million on hand.
McConnell is expected to face a strong challenge from Democrat Alison Lundergan Grimes, Kentucky's 34-year-old secretary of state who announced her candidacy last week.
Grimes, a lawyer from a well-connected Kentucky family, launched her bid with tough words for the 71-year-old McConnell, declaring he has lost touch with Kentucky voters.
