LAS VEGAS (AP) — President Obama's allies argue that he will help underwater homeowners more than Mitt Romney.

An array of Democratic officials held a press conference on Friday to tout the president's housing record and slam his Republican rival. They included former Congresswoman Dina Titus and San Antonio Mayor Julian Castro, who spoke at the Democratic National Convention.

They reminded voters that Romney said before the Nevada primary that the housing market must "hit bottom." Two-thirds of Vegas homeowners owe more than their houses are worth.

The event follows a report in investigative journalist Bob Woodward's new book that Obama told his advisors not to roll out an aggressive housing policy after his election. The Romney campaign said the president has had four years to fix the problem and can't point fingers now.
