Contenders set for 'Daily Show'

Four presidential candidates are lined up to visit Jon Stewart on "The Daily Show" over the next three weeks as Comedy Central's satirical news review ramps up its "Indecision 2008" coverage.

Sen. Joseph R. Biden Jr., the Delaware Democrat, is first up this Wednesday. Biden appeared on "The Daily Show" last winter on the day he announced his candidacy.

Republican Sen. John McCain makes his 10th appearance on Aug. 16, followed by another Republican, former Wisconsin Gov. Tommy Thompson, on Aug. 20.

On Aug. 22, Democratic contender Sen. Barack Obama comes back to the show for a second time, his first as a declared candidate.
