It's game on in Kentucky, in what could end up being the most expensive and nasty 2014 Senate race in the country.
One day after Kentucky Secretary of State Alison Lundergan Grimes, who many in the Democratic party consider their best hope to unseat Senate Republican Leader Mitch McConnell in next year's midterm elections, announced that she'll challenge the longtime GOP senator, and the emails from both sides are flying.
"Alison Lundergan Grimes stood proudly at the Democratic National Convention to nominate Barack Obama, who is now following through on his 2008 promise to destroy the coal industry in essence declaring a war on the state of Kentucky and the middle class families who call it home," declared National Republican Senatorial Committee Communications Director Brad Dayspring, in an email Tuesday morning.
It's part of a strategy by national Republicans and the McConnell campaign to tie Grimes to President Barack Obama, who lost Kentucky by 23 percentage points in last November's election.
"The fact that Mitch McConnell chooses to play politics on behalf of special interests while allowing student loan rates to double on more than 123,000 Kentucky students is exactly the kind of dysfunction and partisanship that's earned him the title of least popular Senate incumbent in the country," responded Justin Barasky, a spokesman at the Democratic Senatorial Campaign Committee, in an email to reporters a few hours later.
His email also described the five-term McConnell as "the walking, talking embodiment of everything that's wrong with Washington."
The Democrats strategy is just as clear as their Republican counterparts. They want to make this contest all about Mitch McConnell and his three decades in the nation's capital.
"If the race is about Barack Obama, we lose. But Democrats will have the resources to make this a race about McConnell, and if it is, we win," says a Democratic strategist with experience in Kentucky, who asked for anonymity to speak more freely.
Starting in March, when actress and activist Ashley Judd announced that she would not challenge McConnell, Grimes came under pressure to announce her intentions one way or another, with some national Democrats touting her as a top potential candidate.
Grimes, 34, a Lexington attorney who cruised to victory in 2011 as Kentucky secretary of state, is the daughter of a former Kentucky Democratic party chairman with close ties to former President Bill Clinton.
Even before she announced her candidacy Monday, Grimes had already come under attack, both by an internet ad put out by the McConnell campaign that poked fun at the amount of time she was taking to make a decision, and by a pro-McConnell independent group that went up with an ad that called her "Obama's cheerleader in Kentucky."
McConnell, 71, is infamous for taking the attack to his political opponents, and he quickly welcomed Grimes to the race by linking her to the president.
"Accepting the invitation from countless Washington liberals to become President Obama's Kentucky candidate was a courageous decision by Alison Lundergan Grimes and I look forward to a respectful exchange of ideas," said McConnell in a statement.
And there was a similar message from the NRSC.
"Kentuckians have absolutely no reason to send Alison Lundergan Grimes to Washington to help pass the policies of a President whom they adamantly oppose and to elect a liberal Senate Leader who declared, 'coal makes us sick,'" said NRSC Executive Director Rob Collins.
"She worked to put him in office. She worked to get him re-elected. You can't de-link the two," a Republican source with knowledge of Bluegrass politics told CNN.
A top Grimes adviser says that strategy won't work.
"Anyone who knows Alison Lundergan Grimes knows that she's her own person. I don't think that Sen. McConnell's trickery will work. Kentucky voters won't buy into those false attacks," Jonathan Hurst, a senior Grimes political adviser, told CNN.
Republicans also attacked Grimes for her Monday announcement. The subject line of Dayspring's daily morning email from the NRSC was "Worst Launch Ever."
And McConnell campaign manager Jesse Benton added that "we hate to see someone flounder so badly, so we decided to give Alison a helping hand," in an email premiering a web video that mocked Grimes announcement.

The Grimes campaign says Monday's announcement was not a rollout.
"Yesterday Alison was simply announcing her intentions to run. I'm certain when we do our rollout, you will see that this will be a top tier campaign and we will have the most professional organization in the state," responded Hurst.
In his five Senate elections, McConnell has only once topped 55% of the vote, and Democrats, touting polls that suggest a close contest, consider McConnell vulnerable. But he has a large war chest, with $8.6 million cash on hand at last check. McConnell raised $20 million for his 2008 re-election, a cash haul that he's expected to top this time around.
The Democratic strategist says Grimes and her allies can stay competitive when it comes to the battle for campaign cash: "You cannot overestimate the desire among Democrats to defeat McConnell. There is nothing that unites Democrats more than wanting to beat McConnell. He's sitting on a mountain of money, and I'm sure he's going to raise millions more, but McConnell's going to need it because Democrats are going to have the resources to take him out."
