GOP Blocks Bill That Would Require Disclosure of Large Campaign Donors

I wonder how the media will explain the vote on a bill that would inform the public about the large donors to "public welfare" organizations that are used to fund political campaigns.  Republican senators voted as a block to defeat the bill.  That should make it difficult for the media to blame both parties for undermining the electoral process.  One party voted to block disclosure, and the other party voted to protect the identity of large donors who use their money to purchase political favor.
