The vast majority of chief executives of major U.S. corporations are against Donald Trump, said Roger Altman, deputy treasury secretary during the Bill Clinton presidency.
"There are a group of people on ... [Hillary] Clinton's behalf who have been recruiting business leaders to support her," Altman told CNBC's "Squawk Box" on Thursday. The CEOs approached are "overwhelmingly anti-Trump," added the founder of investment banking advisory firm Evercore Partners.
But in the wake of last week's Republican convention and continued damage to Hillary Clinton's reputation from the latest email scandal, just 52 percent of Wall Street respondents to the July CNBC Fed Survey see the Democratic nominee prevailing in November, a sharp drop from 80 percent in the April and June surveys.
Altman said it all comes down to the economy. "You start with the economic record of both President [Bill] Clinton and President Obama — and you contrast that to records of recent Republican presidents — it's just a historical fact that they're records were strong records."
Critics of Obama and by extension Clinton's Democratic bid for the White House would point to the 2008 financial crisis as a factor skewing a direct economic-record comparison.
