Sen. Mitch McConnellMitch McConnellOvernight Finance: Inside Trump's tax plan | White House mulls order pulling out of NAFTA | New fight over Dodd-Frank begins Dem rep: Trump's tax plan as believable as 'magic, unicorns or Batman' GOP leaders, top tax writers: Trump principles will be 'critical guideposts' MORE (R-Ky.) and an outside conservative group launched a new barrage of campaign ads Tuesday against a prominent Democrat, Kentucky Secretary of State Alison Lundergan Grimes, who has yet to even announce if she'll challenge the Senate minority leader in 2014.
The Web ads will run on Google search and social networks.
The ad’s are set to run at the same time the pro-McConnell Kentuckians for Strong Leadership (KLS) airs its own attacks in broadcast and cable markets.
The Republican offense follows an air attack from two Democratic groups, Senate Majority PAC and Patriot Majority USA, which portrayed McConnell as a long-in-the-tooth lawmaker who has overstayed his welcome in Congress.
McConnell's ad reflects the latest attempt by the five-term senator to insulate himself against a reelection threat.
With more than $8.6 million cash on hand, McConnell can afford the slow trickle of relatively inexpensive Web ads this far out from the 2014 election.
It’s a continuance of what McConnell called in a recorded private conversation the “Whac-A-Mole” period of the campaign. The comment was recorded by a Kentucky progressive activist last winter.
“When anybody sticks their head up, do them out,” he told aides.
One Kentucky GOP operative said the decision by McConnell and KSL to target Lundergan Grimes is meant to strike some fear into her — and every other prospective Democrat.
"Our aim is to convince [Lundergan Grimes], and any Democrat, that this is a fool's errand,” the operative said.
“They all need to know that this is going to be a long road and a difficult road ... It's not going to be fun and games.”
Though Democrats believe McConnell to be vulnerable, a handful of potential candidates have already turned down the opportunity to run, wary of what Kentucky politicos agree will be a difficult fight.
McConnell's campaign had previously mocked Democratic efforts to recruit a candidate in Kentucky. One Web ad showed Judd saying that “Tennessee is my home."
Lundergan Grimes, 34, emerged as the strongest remaining Democrat after Judd decided in March against running.
A Democratic poll conducted for Senate Majority PAC showed her tied with McConnell. A separate survey from a GOP pollster gave McConnell a 7-point lead.
Lundergran Grimes has been under heavy pressure from a number of prominent Democrats to make a decision on the Senate campaign.
Rep. John YarmuthJohn YarmuthTrump becomes wild card in spending fight House Democrat introduces bill to amend presidential removal procedures CBO: Budget deficits, debt to reach record highs in 30 years MORE (D-Ky.) said last month she was doing a “disservice to the party” by putting off an announcement because other potential candidates were waiting to learn her plans.
The decision is a high stakes one.
An unsuccessful Senate campaign could jeopardize Lundergan Grimes’s political future in the state.
She won the most votes of any statewide Democrat in 2011, and is also said to be considering a future run for attorney general.
The McConnell ad plays off of Democratic frustration about the waiting game.
It features actors impersonating President Obama, Kentucky Gov. Steve Beshear (D), Rep. John Yarmuth (D-Ky.), former President Clinton and former Senate candidate Harvey Sloane.

The message from Yarmuth urges Lundergan Grimes to run because "McConnell sucks," a reference to criticism he lobbed at the senator recently
Kentuckians for Strong Leadership, meanwhile, is trying to saddle Lundergan Grimes with the baggage of Obama's unpopularity in the state. He lost Kentucky by more than 20 points in 2012.
The group’s ad describes her as “Obama's cheerleader in Kentucky."
Even without a candidate, Democrats are stepping up their own attacks on McConnell.
As part of an extended campaign against McConnell, Senate Majority PAC and Patriot Majority USA are launching new ads on Google, Facebook and the Internet radio service Pandora suggesting McConnell's nearly 30-year tenure in Congress is too long.
The groups have spent an initial $250,000 on their first round of ads and are backing the new web ads with an additional $10,000.
