Is caging wrong ?

Voter fraud is a bad thing, isn't it? If this cuts down on that, wouldn't that be a good thing? How this disenfranchises minorities is beyond me. They need to follow the same rules as anyone else, don't they?

Absolutely. It should be noted that they do this not in areas that they necessarily suspect voter fraud, but in areas where they think that the constituents will be voting for the opposite party.

As for that "registered letter that the voter has to sign", often it is packaged in a way as to appear like junk mail, with the intention that the voter will throw the mail in the trash without opening it.

I have only heard of Republicans doing down low stuff like this.

Examples of proven or alleged political caging

From the Washington Post: "In 1981, the Republican National Committee sent letters to predominantly black neighborhoods in New Jersey, and when 45,000 letters were returned as undeliverable, the committee compiled a challenge list to remove those voters from the rolls. The RNC sent off-duty law enforcement officials to the polls and hung posters in heavily black neighborhoods warning that violating election laws is a crime." Republicans however, denied that black voters were the target. An attorney for the RNC, Bobby Burchfield, stated that "troubling reports" of fictitious names such as Mary Poppins were appearing on Ohio's rolls and that is what prompted the challenges.

The Washington Post[11]: "In 1986, the RNC tried to have 31,000 voters, most of them black, removed from the rolls in Louisiana when a party mailer was returned. The consent decrees that resulted prohibited the party from engaging in anti-fraud initiatives that target minorities or conduct mail campaigns to 'compile voter challenge lists.'" The Republican National Committee reportedly stopped the practice following the consent decree in the 1986 case, but allegations of RNC-conducted voter caging arose once again in the 2004 elections.

In October 2004, the BBC Newsnight program reported on an alleged George W. Bush campaign caging list, the existence of which suggested that the campaign might have been planning illegal disruption of African American voting in Jacksonville, Florida. The BBC obtained a document from George W. Bush's Florida campaign headquarters that was inadvertently e-mailed to the parody website GeorgeWBush.org. The program reported that the e-mail attachment contained a list of 1,886 voter names and addresses in largely African-American and Democratic areas of Jacksonville. Democratic Party officials and a number of journalists allege that the document is a caging list that the Bush campaign was going to use to issue mass challenges to African-American voters, in violation of the court ordered 1982 and 1987 consent decrees. Although Florida statutory law allows the parties to challenge voters at the polls, this practice is not allowed if the challenges appear to be race-based. Court documents produced during limited discovery in a challenge to use of cagings list in Ohio, revealed clear intent to use caging lists to challenge voters. Specifically, in the US District Court, District of New Jersey, Civil Action No. 81-3876, exhibit D, filed 10/29/04 and entitled "Declaration_of_Caroline_Hunter_and_emails_exh_d", emails exchanged between RNC operatives (Blaise Hazlewood, Caroline Hunter, Terry Nelson, and Tim Griffin), Bush-Cheney '04 campaign workers (Christopher Guith, Coddy Johnson, Robert Paduchik, and Dave DenHerder) and the Ohio Republican Party personnel (Mike Magan) revealed involvement of these entities in caging operations and intent to utilize the caging lists to challenge ballots in Ohio and other states[12]. Furthermore, these email exchanges also revealed concern about GOP fingerprints with ballot challenges based on caging lists in states that did not have flagged voter rolls[13]. The concern about GOP involvement in the email sent by Tim Griffin to Christopher Guith and others may have reflected knowledge of the fact that the RNC is prohibited by Consent Decrees from involvement in ballot security measures such as caging, when the measures have racial bias. Regardless of the intent of caging list design, there are no documented voter challenges based on caging lists in the 2004 elections.

The list came to light because of numerous e-mails accidentally addressed by, among others, Republican campaigners to the georgewbush.org anti-Bush site instead of the georgewbush.com Bush campaign site. Two of these e-mails had the subject line "Re: Caging" and contained Microsoft Excel spreadsheet file attachments called "Caging.xls" and "Caging-1.xls".[14][15].

Investigative reporter Greg Palast initially received the emails from the owner of georgewbush.org, and in a recent interview[when?] has drawn a link to the scandal surrounding the Alberto Gonzales U.S. Attorney firings, claiming that the firings are part of a wider effort by Republicans to use caging to "steal the 2008 election."[16]

In December 2007, Kansas GOP Chair Kris Kobach sent an email boasting that "to date, the Kansas GOP has identified and caged more voters in the last 11 months than the previous two years!"[17]

On September 16, 2008, Obama legal counsel announced that they would be seeking an injunction to stop an alleged caging scheme in Michigan wherein the state Republican party would use home foreclosure lists to challenge voters still using their foreclosed home as a primary address at the polls. [18] Michigan GOP officials called the suit "desperate."[19]

What is so wrong about verify if someone is legally able to vote? The only ones who need to worry about it are those who are not following the law.
