President Barack Obama says he intends to win the 2012 election because he's got "better ideas."

Speaking at a fundraiser Tuesday night for his re-election campaign, Obama said his ideas are based on the notion that Americans should share in the nation's burdens and successes.

First lady Michelle Obama introduced her husband at the 400-person event at New York's Gotham Hall and urged his supporters to "have his back."

Tickets for the event ranged in price between $2,500 and $35,800 a person, the legal maximum. The money goes to Obama's re-election campaign and the Democratic National Committee.

Obama speaks to the U.N. General Assembly on Wednesday.
