Oct. 30 -- WISCONSIN -- Training poll workers to mislead? Romney campaign documents encourage the candidate's poll workers to hide their affiliation to the public and to election workers, the liberal claims.

Oct. 26 -- FLORIDA -- Duplicate absentee ballots created.

Oct. 24 -- FLORIDA -- FBI brought in to investigate bogus voter purge letters. The effort targeted prominent Republicans in 28 Florida counties, a group alleges. The letter asserted it had received information from the state “bringing into question your eligibility as a registered voter.” It directs the recipient to “please stop by our main office with any original documentation that demonstrates U.S. citizenship” and says vote fraud is a felony. Read the full story

Oct. 23 -- OHIO, WISCONSIN -- Dozens of voter fraud billboards coming down. Civil rights groups had said the billboards, paid for by an anonymous group, were a brazen form of voter intimidation.

Oct. 23 -- VIRGINIA -- Federal probe demanded.

Oct. 23 -- PENNSYLVANIA -- More billboard complaints. Billboards advertising a state law on voter IDs are confusing people and could suppress voter turnout, voter advocates told the Philadelphia Daily News. A court delayed imposition of the law until 2013, but some billboards, part of a $5 million state advertising campaign, remain. Examples include 10 billboards in primarily Hispanic neighborhoods showing a woman with a driver's license saying in Spanish: "This Election Day, if you have it, show it.'' Read the full story

Oct. 22 -- OHIO, ARIZONA -- Whoops, wrong Election Day.  Authorities in a swing county in Ohio sent out notices to some voters announcing the elections as Nov. 8 instead of Nov. 6.

Officials called it an honest mistake. Read the full story

Oct. 16 -- MARYLAND -- Online voter registration suspect? A voting rights group and some of the nation’s leading researchers on election technology are urging Maryland voters to check the accuracy of their online voter registration files after warning that the data had been left vulnerable to tampering. The letter warned that anyone with access to a Maryland voter’s full name and birth date could exploit a simple online tool to change the voter’s address, party affiliation or other information. Such changes, especially a change of address, could lead to a voter’s ballot not being counted normally on Election Day. Ross K. Goldstein, deputy administrator of the elections board, said the state had taken unspecified steps to protect voter files. Read the full story.
