Once upon a time, young voters, you remember Barack Obama: cool, hip, The Future. But not anymore. Now, he’s just a guy who wants your mom to nag you to buy the insurance policy he’s having trouble selling:

The Obama administration and its allies need lots of healthy young adults to sign up for insurance this fall to make the president’s health-care law successful.

So they are going after their moms.

They put up Web ads on Facebook and Allrecipes.com alongside slogans such as “Moms know best: ‘Get yourself health insurance.’” They have enlisted the help of parent-activist groups such as Moms Rising, which has already begun mobilizing its vast network of more than 1 million members and 3 million e-mail subscribers on behalf of the health-care law.

They are collaborating with Elle and Cosmopolitan magazines, organizing mom-oriented wine-and-cheese parties and preparing commercials that will run during shows popular with mothers, such as “Good Morning America.”

Democrats are hopeful that a nagging mother will be hard to say no to:

“In the end, it will be the moms of America who are going to decide if their families get coverage,” said Celinda Lake, a Democratic pollster who has conducted focus groups for health exchanges in three states. “They will decide and then insist their children and husbands sign up.”

But “[m]others, however, have been turned off by the divisive nature of the debate over the law, Lake said. Even for mothers engaged in politics, the law’s close association with President Obama is not always a plus.”

That’s right: Mom finds the guy a little too pushy, too.

Of course, the whole point of getting young people to sign up for Obamacare is that it’s not in their best financial interest; they’re supposed to overpay for the insurance they receive, to subsidize the older, sicker people in the program. Which is why the effort to dragoon Mom into nagging you may not work: because at the end of the day, your mother usually knows best.
