NEW YORK (AP) — 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.
