Top lawyers for the Democratic Party and Sen. Barack Obama this week filed a complaint in federal court in Michigan alleging that state Republicans were scheming to strip the right to vote from people living in homes that have been placed on foreclosure lists.
Democrats made their move after James Carabelli, the chairman of the Republican Party in Macomb County, Mich., allegedly told a locally run Web site, "We will have a list of foreclosed homes and will make sure people aren't voting from those addresses."
Carabelli has denied ever making such a statement and has asked the Michigan Messenger Web site for a retraction.
In the last two months of this tense and heated presidential race, a new season has arrived that usually brings an increase in allegations of disenfranchised voters and voter fraud, and the fanning out of an army of lawyers across the country.
Typically, as in the Michigan case, the lawyers divide neatly down party lines, with Democrats arguing that the voters of some of their key constituencies are under attack and Republicans countering that states need to be vigilant to combat instances of voter fraud.
On Wednesday, the Republican National Committee called the Michigan legal filing "reckless" and accused the Democrats of a national strategy to engage the federal courts "without factual basis."
Sean Cairncross, the RNC's chief counsel, said, "The RNC would not, has not, and will not use foreclosure lists as the basis of any challenge."
A Democratic lawyer involved in the suit said the party nevertheless plans to "quickly" continue the suit and file a motion for preliminary injunction.
In the Michigan complaint, the Democrats accuse the Republicans of a "long history" of voter suppression tactics.
The ACLU and other voting rights groups have filed suit in states including Mississippi, Tennessee and Alabama targeting laws they say disenfranchise voters.
On its Web site, the RNC has a section dedicated to allegations of voting fraud. On Wednesday, the committee sent out a press release regarding a story in the New Mexico media that 1,000 new voter registration cards received in one county might be frauds.
"The season has begun," said RNC spokesman Danny Diaz.
The political committees have even engaged in dueling conference calls featuring their top lawyers.
The issue escalates each election year, with experts saying that it is becoming more intense with each cycle.
Last term, it even made its way to the Supreme Court in the form of a challenge to Indiana's voter identification law, one of the strictest in the country, in a case known as Crawford v. Marion County Election Board.
The court upheld the law finding that "flagrant examples" of voter fraud have been documented "throughout this Nation's history." Justice John Paul Stevens, the author of the lead opinion, wrote, "There is no question about the legitimacy or importance of the State's interest in counting only the votes of eligible voters."
The Republican National Committee filed a brief in the case in defense of the Indiana law.
"This is not a conspiracy," wrote RNC lawyers. "Fraud and the perception of fraud in the election process erode voter confidence, casts doubt on election results" and "undermines everything the Republican Party works to accomplish."
