From CNN today:

In St. Louis, Missouri, Lisa Foreman said she went to vote in her precinct where improperly calibrated machines would only select Republican John McCain for president. She said workers there were trying to fix the problem.

“We stood in line for three hours. Eventually we had to move to paper ballots,” Foreman said.

In Philadelphia, Pennsylvania, Regina Hollis said she ran into problems with her voter registration, even though she’s lived at the same address for the past five years.

“Today I go to vote, my name is not in the book and I had to fill out a provisional ballot,” Hollis.
