Romney aide trades on political ties

The story of Solamere offers a rare glimpse into the intersecting worlds of Romney’s business and political operation, which continues to employ Zwick as chief fund-raiser for the 2012 campaign. Although campaign finance specialists say his overlapping missions are permitted by law, some ethics watchdogs say the arrangement presents an appearance that key political contributors could be rewarded with business opportunities.

“This setup screams what’s wrong with our broken system,’’ said Bob Edgar, chief executive of Common Cause, a national nonprofit advocacy group that frequently speaks out against the influence of money and lobbying in politics. “This is a business deal, and Romney is the investment. If he’s elected, they will have access and influence at the White House. If he’s not the next president, they’ll still make a bundle on the deal. Either way, they will be rewarded.’’

Mitt Romney and Solamere’s principals declined through representatives to be interviewed. Solamere said in a statement that there was no consideration given to political connections or support in Solamere’s business strategies and that the firm “adhered to the highest ethical standards.’’ Romney spokeswoman Gail Gitcho said Solamere and the candidate’s political interests are completely separate.

Solamere does not disclose the identities of its investors. Although the prospectus obtained by the Globe lists equity and venture firms that would be potential investment targets, the company would not confirm where it has placed its money. The lack of transparency makes it difficult to verify whether Zwick is appropriately managing his overlapping roles, critics say.
