Congress is meeting today to count votes cast by the Electoral College and certify the winner of the presidential election.
But some House Democrats say reports of election problems in Ohio raise doubts about the legitimacy of the state's 20 electoral votes. They plan to challenge Ohio's slate. If at least one senator joins the effort, the two chambers will consider the objection.
So far, no senators have said they will object. Even if one did, both chambers are controlled by Republicans, so President Bush still would be guaranteed a victory.
The challengers say they are objecting to call attention to Ohio's voting problems, which they have likened to Florida's contested vote in 2000 when Bush defeated Al Gore for the White House.
