Newt and the others saw this coming in the primary, but they let the GOP elite bully them into dropping the subject. A huge mistake.
Sure Obama did it in 2008 (releasing 2000-2007) and demanded Hillary do the same but so what?
Candidates aren't required to release tax returns. McCain and prior didn't release a vast back history of returns.
Why let Obama set this standard while he hides everything else?
It's a case of phony disclosure and Junior High, "I showed your mind, you show me yours."
I did see in the WA Post the McCain campaign got over 20 years worth of tax returns from Romney as part of the VP vetting process.
This was Romney's reply ahead of the South Carolina primary.
"You know, I looked at what has been done in campaigns in the past with Sen. McCain and President George W. Bush and others. They have tended to release tax records in April or tax season. I hadn't planned on releasing tax records because the law requires us to release all of our assets, all the things we own. That I have already released. It's a pretty full disclosure. But, you know, if that's been the tradition and I'm not opposed to doing that, time will tell. ... I sort of feel like we are showing a lot of exposure at this point. And if I become our nominee, and what's happened in history is people have released them in about April of the coming year, and that's probably what I would do."
