George Demos

On October 6, 2013, he announced he would seek the Republican nomination to run against Congressman Tim Bishop. On June 24, 2014 he lost the primary election to New York State Senator Lee Zeldin.

Citing his impending wedding, Demos withdrew from the race May 25, 2012.

Demos announced another run for Congress Monday, August 8, 2011. Shortly after his announcement, Demos called Randy Altschuler, the other announced Republican candidate, "unelectable" for losing in a district with a 30,000 Republican voter edge in 2010. Demos also chided Altschuler for taking the same position as incumbent Congressman Tim Bishop on the 2011 debt ceiling compromise.

In June 2011, it was reported by the Project On Government Oversight that the Appellate Division of the Supreme Court of the State of New York reopened an investigation into Demos for allegedly disclosing the identity of a JPMorgan Chase whistleblower while Demos served as an attorney at the SEC. Initially the 10th Judicial District Grievance Committee disposed of the allegations. However, the court committee transferred the investigation to "avoid the appearance of impropriety." In a letter dated September 23, 2011, the Third Judicial Department dismissed the matter again, stating "the Committee has determined that there is an insufficient basis for a finding of professional misconduct."

Demos vied in 2010 for the Republican nomination to compete for the congressional seat of Democrat Tim Bishop on Long Island in New York State in the November 2010 election, coming in second in the primary. His three-way primary included Christopher Nixon Cox, the grandson of President Richard Nixon and Randy Altschuler, a businessman.

John Jay LaValle, Suffolk County Republican chairman, opined in February 2010 that Demos was a qualified and "extraordinary" candidate for the Republican Party's nomination to be a congressman in the 1st District from eastern Long Island. It was Demos's first run for office.

In April 2010, Demos said that the Suffolk Conservatives were "inexplicably" preparing to endorse Altschuler. Demos called Altschuler a "pro-choice, outsourcing proponent" and former member of the Green Party, which embraces "radical Marxist ideologies." In July 2010 he issued a new radio ad, in which he identified himself as the "only Conservative" in the contest. That month he also said that Tea Party members had been supporting his candidacy.

In August 2010, he accused Altschuler of stealing another candidate's press releases, pointing to identical releases from Altschuler and Doug Hoffman, a candidate in for another New York congressional seat who uses the same consultant on some issues. That month he also accused rival Chris Cox of using his father-in-law to-be, Catsimatidis, for "dirty tricks".

In the September 2010 primary, Altschuler finished first with 45 percent of the vote, Demos had 30 percent, and Cox was third with 24 percent.

Demos is married to Chrysa Tsakopoulos, daughter of the real estate developer Angelo Tsakopoulos. His sister-in-law, Eleni Kounalakis, is the current Lieutenant Governor of California. She served as the United States Ambassador to Hungary from 2010 to 2013 and was the first Greek American woman to serve as ambassador.

He used the strategy firm Shawmut Group, which was formed in 2008 by Mitt Romney's advisors. In January 2010, Demos appointed to his political team Rob Cole, a former advisor to former New York Governor George Pataki, and a member of Romney's 2008 campaign team. That month, Demos also announced that he had raised more than $300,000 for his campaign. At the end of 2009, his campaign had $275,000. He also issued his first TV ad, a 30-second commercial that attacked Bishop for supporting "reckless" fiscal policy.

Demos prosecuted white collar fraud as a prosecutor at the U.S. Securities and Exchange Commission (SEC) between 2002 and 2009.
