FACTBOX: Presidential candidates economy plans

(Reuters) - Presidential candidates have been outlining their plans to revive the sagging U.S. economy. Following are some from the three main candidates:

DEMOCRATIC NEW YORK SEN. HILLARY CLINTON

* Called for a second stimulus package with a $30 billion fund to put cash into the hands of local governments and nonprofit organizations to buy and resell properties to low-income people or turn them into affordable rental housing units.

* Plans to introduce legislation to provide legal protection for mortgage servicers who help struggling homeowners to modify their mortgages.

* Supports expansion of Federal Housing Administration's capacity to guarantee restructured mortgages, in line with legislation proposed by Democrats Rep. Barney Frank of Massachusetts and Sen.

* Called for greater government regulation of the U.S. financial system and proposed a new $30 billion economic stimulus plan to help homeowners.

* The $30 billion plan includes $10 billion foreclosure prevention fund to help people keep their homes. It also includes $10 billion in relief for state and local governments hit hardest by housing crisis.

* Outlined six "core principles for reform" that would give the Federal Reserve supervisory authority over any financial institution to which it might make credit available and calls for reform and streamlining of financial regulatory agencies.

* Wants to repeal a provision in bankruptcy law so ordinary families can modify terms of home mortgages.

* Proposed a 10 percent mortgage tax credit for middle-class Americans.

REPUBLICAN ARIZONA SEN. JOHN MCCAIN

* Proposed a suspension of the 18.4 cent federal gas tax and 24.4 cent diesel tax during the summer.
