(CNN) – Barack Obama and Joe Biden are set to hit several battleground states following the conclusion of the Democratic Nation Convention Thursday evening, the Obama campaign announced Wednesday.

The tour is dubbed "On the Road to Change,” and will feature stops in Michigan, Ohio, and Pennsylvania – all states expected to play a critical roll this fall.

The trip will be the first extended campaign leg featuring Obama and Biden together, as well as both candidates’ spouses.

Gov. Tim Kaine shoots back against criticism from Karl Rove.

(CNN) – It was a tough retort from Gov. Tim Kaine, a Democrat from Virginia.

Kaine responded Sunday to comments made by Republican strategist Karl Rove earlier this month criticizing Kaine's potential vice presidential credentials.

On CBS' "Face the Nation," Rove jabbed at the governor, saying "again no disrespect to Gov. Kaine. He's been a governor for three years. He's been able but undistinguished. I don't think people could really name a big, important thing that he's done."

The Democratic governor - who is rumored to be on Barack Obama's potential VP list - pointed out that his state was voted best for business three years in a row by Forbes.com and said "maybe Karl Roves and the Republicans don't care about business climate, that would explain why we're in the situation that we're in".

"Governing Magazine was also named Virginia as the top governed state in America," Kaine told reporters, "maybe to Karl Rove that isn't an achievement that would explain a federal government that couldn't respond to a hurricane a Katrina and couldn't figure out how to start and manage a war."

Kaine spoke to reporters in Washington after shooting a televised interview Sunday morning.

By the way, in the 2008 Governing Magazine ranking, Virginia shares its top A- rating with two other states: Washington and Utah.

(CNN) - John McCain was tight-lipped Friday afternoon when it came to answering any questions about former U.S. Senator and Democratic hopeful John Edwards's admittance to having an extramarital affair. Edwards acknowledged he had had an affair with a former aide in 2006 but denied being the father of her baby. McCain told reporters "I don't have any comment on that" during a press conference in Rogers, Arkansas.

In Nevada, New York Senator Hillary Clinton said her "thoughts and prayers are with the Edward's family today" when asked if she thought her party would suffer any repercussions because of the scandal. Senator Clinton held an impromptu press conference following a campaign event in Las Vegas for Barack Obama where the statement was made.

McCain is targeting the Cuban-American vote in Florida.

(CNN) – John McCain’s campaign is running a Spanish-language radio ad in Florida aimed at Cuban-American voters.

The 60-second spot, titled "Cuba prisoners," is narrated by Roberto Martin-Perez, a former political prisoner in Cuba who now lives in Miami and serves as the spokesperson for the Association of Cuban Political Prisoners.

In the ad, Martin-Perez calls Raul Castro a dictator "just like his brother" Fidel, who will continue to suppress human rights and freedom of speech on the island.

The spot jabs Barack Obama for his pledge to meet with leaders of hostile countries like Cuba.

"Instead of talking to Raul Castro, John McCain insists that all political prisoners be freed," Martin-Perez says, adding that McCain supports the men and women who "fight for Cuba’s freedom."

"As a former prisoner in Vietnam who saw many cruelties," the narrator says, "John McCain knows that Cuba will not be freed with concessions to the dictatorship."
