FACTBOX: Faces and facts in congressional election

(Reuters) - For the first time since Bill Clinton headed the party's ticket in 1992, Democrats won control in Tuesday's election of both chambers of Congress and the White House.

Here's a look at some of the facts and faces in the election as well as the new 111th U.S. Congress that convenes in January.

* Democrats gained at least five seats in the 100-member Senate, boosting their majority to 56. Four races remained too close to call on Wednesday. If Democrats win all four, they would, for the first time in 30 years, have the 60 seats needed to clear Republican procedural hurdles that can kill legislation.

* With results of seven races in the 435-member House of Representatives yet to be determined on Wednesday, Democrats counted a net gain of 20 seats, boosting their majority to 255.

* Two former Democratic governors, Mark Warner of Virginia and Jeanne Shaheen of New Hampshire, won seats held by Republicans -- retiring Sen. John Warner and Sen. John Sununu, respectively.

* Republican Sen. Elizabeth Dole of North Carolina, wife of 1996 Republican presidential nominee Bob Dole, was unseated by Democratic state Sen. Kay Hagan.

* Democratic U.S. Rep. Tom Udall won the seat being vacated by retiring Republican Sen. Pete Domenici of New Mexico, and his cousin, Democratic Rep. Mark Udall of Colorado, won the seat being vacated by Republican Wayne Allard.

* With no one getting a required majority of the vote, a three-way race in Georgia involving incumbent Republican Sen. Saxby Chambliss appeared headed toward a runoff next month.

* Winners had also yet to be declared in three other Senate races involving Republican incumbents -- Sens. Norm Coleman in Minnesota, Gordon Smith in Oregon and Ted Stevens in Alaska. All three held slim leads on Wednesday.

* One of the relatively few Democrats who had a bad election night was Rep. Tim Mahoney of Florida. Just weeks after admitting having had extramarital affairs, the first- term lawmaker was unseated by Republican attorney Tom Rooney.
