Paul Blumenthal writes: Even in the era of unbridled campaign contributions, Irving Moskowitz’s $1 million donation in February to American Crossroads, the Karl Rove-linked super PAC, is eye-catching.

Although he has funded Republican politicians and organizations in the past, his $1 million donation to American Crossroads is his biggest contribution to U.S. electoral politics to date. Moskowitz did not respond to requests for comment from The Huffington Post. American Crossroads told HuffPost that it does not comment on its donors.
