Currently, the Democrats benefit from the voter fraud, nominally through a misapplication of the 1973 Voting Rights Act, predominantly in Florida, but one in eight voting registrations are flawed and/or illegal , while the Republicans benefit from the below market labor costs, so neither party actually wants the practice of illegal immigration stopped. Here is the NY Times article on it from the Pew Center for the States: http://www.nytimes.com/2012/02/14/us/politics/us-voter-registration-rolls-are-in-disarray-pew-report-finds.html?_r=0 [nytimes.com]
What a bullshitter you are. The article basically says there are lot of errors in the registration systems to the point that dead people are still in the roles (not that other people are using those identities to vote), that people that move often end up registered in more than one state (not that they are voting in more than one), that a high percentage of registrations contain data errors serious enough that the voter will not receive a ballot (flawed, but not "illegal" as you insinuate), and that approximately 1 in 4 eligible voters isn't even registered. It then says that Democrats want to make it easier to register people, but that Republicans don't want that because of fear that it could introduce fraud. The last election highlighted several occurrences of voter fraud, none of which being identity fraud that the Voter ID laws Republicans have been pushing would have stopped, and the most serious being perpetrated by Republicans.
