I have to make a correction:
Target did not directly contribute to the Republican candidate Tom Emmer, rather they gave money to Minnesota Forward, who in turn used that money, plus other contributions to support Emmer.
Also, the Deluxe CD is not exclusive to Target. It's available on iTunes, but Target was looking for rights to sell that exclusive album, which they got after the meeting.
However, the above does not change my stance about Target's behavior. Before their meeting with Gaga, Target has been involved with the gay community. What Target did regarding their donation was to look out for their corporate interest. Their involvement with Lady Gaga (and I'm also reading Ricky Martin and Ellen) is also for corporate interest.
Here's an interview between Billboard's Bill Werde and a representative from Target. Bill does a great job to get beyond the vague concept of 'thoughtfulness' that Target Vice President of Public Relations Dustee Tucker Jenkins was throwing out at him during the interview:http://www.billboard.biz/bbbiz/industry/retail/target-s-public-relations-vice-president-1005042332.story
Target will continue to have donations sent to both major political parties. And considering that many Republicans vote anti-gay (see what's happening at the state level, and how the repeal of DADT was pretty much divided along partisan lines), their money will likely continue get funneled to a candidate who has an anti-gay stance.
I love Lady Gaga, but to put this into perspective, her deal with Target was nothing more than sending Target to the corner for time-out.
