The U.S. Treasury is controlled by Democrats. The IRS scandal involving the approval of tea party groups as non-profit agencies was a political ploy until after the 2012 election was over, plain and simple. It wasn't a scam, it was a power play to get back at conservative elements that could have won more votes for Republicans running for Congress.
The Internal Revenue Service and the news that it was targeting certain groups due to their political leanings was neither scam nor scandal. As we learned in the days and weeks following the revelation of what happened, this was merely some middle management employees of the agency making discriminatory "administrative decisions."
