In case you're tempted to buy the media's "there's no real connection between Obama and ACORN" line, read this from August, 2008:
"U.S. Sen. Barack Obama's presidential campaign paid more than $800,000 to an offshoot of the liberal Association of Community Organizations for Reform Now for services the Democrat's campaign says it mistakenly misrepresented in federal reports. An Obama spokesman said Federal Election Commission reports would be amended to show Citizens Services Inc. -- a subsidiary of ACORN -- worked in "get-out-the-vote" projects, instead of activities such as polling, advance work and staging major events as stated in FEC finance reports filed during the primary."
In other words, Obama lied in his initial filings, mis-characterizing why he was paying ACORN, until after he was nominated.
And, "more than $800,000" to "get-out-the-vote"? That's alot of money for services rendered by a group known to "get-out-the-vote" with fraud.
Of course, the Washington Post dismisses this as "Obama's infrequent ties to the group" way back in "his days as a community organizer in Chicago" "in 1994" and "in 1992".
