Congress is taking its first look at problems voters had in November, including long lines that left many waiting for hours to cast ballots. A rise in the use of provisional ballots delayed the results for days in some cases. And growing photo ID requirements placed on voters by Republican-controlled legislatures in some states sparked intense partisan fights. The Senate Judiciary Committee was to examine last month's balloting during a hearing today on the 1965 Voting Rights Act. The law requires federal approval for election changes in all or parts of 16 states with a history of racial discrimination. The panel's chairman, Democratic Sen. Patrick Leahy of Vermont, described the long lines and new tools for policing voter fraud as evidence of abusive practices intended to disenfranchise minority voters.
