U.S. Sen. John Kerry responded to Republican challenger Jeff Beatty's criticism Sunday, blasting Beatty for not offering a vision for the future of the country.

In an email to PolitickerMA.com, Brigid O'Rourke, a spokeswoman for the Boston Democrat, said Beatty has focused more on personal attacks than on offering his own policy proposals.

"Instead of worrying about prom dates, Jeff should just focus on his own campaign and start talking about what he stands for, because most Massachusetts voters still don't know," O'Rourke said. "Jeff has no clear stances on critical issues like providing health care to Americans, improving education, fixing our economy, or even taxes. All Jeff has been clear on is his support for guns in our schools, his reckless plan to drill our way to energy independence, and the fact that he is a faithful supporter of George Bush and the McCain-Palin ticket."

O'Rourke also strongly denounced Beatty's remarks that Kerry is running for a position in an Obama administration.

"I don't know how much clearer I can be on this," O'Rourke said. "The only office Sen. Kerry is running for is senator from Massachusetts."

O'Rourke also jibed Beatty for that criticism, which implied that Democratic presidential nominee Barack Obama is going to win on Tuesday.

"You know, Jeff Beatty should call George Bush and John McCain if he feels left behind. That's what Jeff's Republican Party has done to Americans," O'Rourke said. "Furthermore, we're certainly glad to see Mr. Beatty is as confident as we are that Senator Obama is going to win on Tuesday."
