There's been a concerted move to the right by the banking industry since the passage of the Dodd-Frank Act in 2010. The industry already tilted slightly Republican for years, but there's been a more distinctive shift over the past two election cycles. Employees and PACs representing the financial sector have given 62% to Republicans and just 38% to Democrats so far this term, and the split for commercial banks is even more apparent, with 70% of their money going to the GOP.
