Good on him!
But he repeatedly has broken with the practice of presidential candidates in both parties in disclosing more. He's refused to release the names of the fundraisers who tap friends and business networks to raise hundreds of thousands of dollars for his campaign, and has said he'll release only two years' worth of tax returns.
I'm delighted to see someone who can push back instead of caving to every political or media demand for more-more-more.
Nobody needs more than 2 tax returns, or the names of everyone you ever met in business, politics or at the local candy store when you were 10. He is doing all that law demands and he has no obligation to offer more.
And he sure as hell doesn't need to open up every fundraiser to the media.
Whiners can claim he's trying to hide something. I say he's showing he has some balls.
