Mitt Romney has been hounded by Democrats for most of 2012 because he had not released enough of his previous years' tax returns. Romney fulfilled the promise he'd made to release his 2011 return. Predictably, Democrats jumped on the fact that although Romney contributed over $4 million to charity in 2011, he only claimed about $2 million of it as deductions. Democrats howled that Romney did this so that his tax rate would match what he's said it was in the past. (Yes, that claim is as ridiculous as it seems. A politician's actions matched his words, and Democrats criticized it.)
However, this serious violation of all things good goes deeper. There are stories that Romney has tried to keep from the public. Lurid tales of Romney helping charities and individuals out financially -- then asking them to keep it to themselves. Not only that, but he has also physically helped people with his time and his efforts. John Hawkins has discovered the truth about Romney, and exposes Romney in his column "7 Incredible Personal Stories About Mitt Romney That You May Not Know."
