The reason it is not secret, WT, is that ACORN is so blatant about what they are doing! College students filmed "voter organizers" and got caught in the act! This is nothing new for Acorn, they have a reputation for it.
What's happening here is something we have never seen before: centrist Clinton Democrats and Republicans are working together to expose the DNC and Obama campaign's illegal activities and orchestrated, coordinated fraud. Both parties are working with federal agents to investigate ACORN, which has been funded with upwards of $800,000 in questionable donations from the Obama campaign in what appears to be the expressed and explicit direction to engineer voter fraud in the general election (I have not personally investigated this). The tactics being employed now in the 15 states currently under investigation are the VERY SAME TACTICS we saw on the ground in Iowa, Texas, Colorado, Nebraska, Indiana, and other states working for Hillary Clinton in the primaries.
And all of this ties back to Chicago.
Where the Obama campaign and DNC are now based.
Obama once worked for ACORN's Project Vote program as its director and trained ACORN volunteers in the early 1990's. Later, as an attorney, Obama had ACORN as a client. Obama successfully represented ACORN, joined by the federal government, in a suit to force Illinois to implement the federal Motor Voter law, which Illinois Republicans feared could lead to voter fraud. ACORN's political action committee has endorsed Obama in his run for the White House.
