Before you dump Santorum, CREW is a leftist group, which is funded by George Soros.

Roll Call reported in January 2008 that CREW files most of its complaints against members of Congress, and "all but a handful... have targeted Republicans". The article stated that CREW had issued press releases against Democrats but usually had not filed complaints against them, with the exception of Senator Mary Landrieu, a conservative Democrat.[34] CREW defended itself to Roll Call:

    "CREW is a nonpartisan organization that targets unethical conduct," [Deputy Director Naomi] Seligman wrote... "Now that the Democrats are in power, they will have opportunities for corruption that were previously reserved to Republicans and it is likely we will see more Democratic corruption."

After the article was published, CREW stated that it was "baseless" and "omitted key facts". CREW also suggested the Roll Call reporter had been prompted by a conversation with Democratic Senator Mary Landrieu, the target of a recent CREW lawsuit at the time.[35]

Roll Call reported that CREW investigated "groups and individuals who are the foes of CREW's donors" as well as a political opponent of one of CREW's board directors, and that CREW refused to disclose its donor list.[34] Donors to CREW include such liberal groups as George Soros' Open Society Institute, Democracy Alliance, Service Employees International Union, the Arca Foundation, and the Gill Foundation.[34][36][37] The Roll Call article also stated that the CREW mission statement had changed since 2005, when it read that CREW "differs from other good government groups in that it sues offending politicians directly" and that it "aims to counterbalance the conservative legal watchdog groups that made such a strong impact over the past decade."
