Senate Minority Leader Mitch McConnell raised $2.2 million in the second quarter, growing his 2014 campaign war chest to $9.6 million, the Washington Examiner has learned.

The Kentucky Republican raised another "substantial" amount for the state GOP, with much of that earmarked to support McConnell's own re-election effort. McConnell had raised $15.4 million for the election cycle through June 30, putting the Kentuckian ahead of the torrid fundraising pace he set during his 2008 campaign, when he raised $21 million.

McConnell has already invested significant funds in building a campaign infrastructure, and he might need it. Kentucky Secretary of State Alison Lundergan Grimes last week launched her campaign to oust McConnell, and she is considered a top-tier recruit for the Democrats. Grimes hails from a Kentucky political family that is close to Bill and Hillary Clinton.

"Senator McConnell has broad, tremendous support and he has once again turned that strength into a prolific fundraising quarter," campaign manager Jesse Benton said. "We are running a presidential level campaign that will make Kentucky proud
and ensure we re-elect our Republican leader."

The Bluegrass State is Republican territory, and McConnell is now favored to win a sixth term.
