Bill and Hillary Clinton, "Not-too-Distant" Grandparents?

The Bushes may not be the only political family hearing wedding bells ringing... and possibly pushing baby buggies.

Chelsea Clinton, on the stump in Pennsylvania with her mom Thursday, said she's "thinking about having my own family in the not-too-distant future."

Appealing to voters at Haverford College, Clinton described herself as not just a "young voter" but a "young woman and someone who is thinking about having my own family in the not-too-distant future, something that will make my mother and grandmother infinitely happy." She was joined by both her mother and her grandmother, Dorothy Rodham.

Chelsea's boyfriend, Marc Mezvinsky, the would-be father of Bill and Hillary Rodham Clinton's grandchildren, has stayed out of the spotlight this campaign season. Though sources say he, along with other good friends of the former first daughter, have joined Ms. Clinton at various stops on the campaign trail, where she has been a tireless voice for her mother's candidacy for the Democratic presidential nomination -- especially on college campuses, which have, by and large, been Barack Obama territory.

Mezvinsky and Clinton already co-parent a dog, a tiny terrier, who has been spotted on the campaign trail with its humans.

Mezvinsky, who works at Goldman Sachs, is the son of two former members of Congress -- Marjorie Margolies-Mezvinsky and Ed Mezvinsky, who is in prison for fraud.
