The Democratic Party's lurch to the left is much like the disruption Republicans felt about decade ago with the rise of the tea party on the far right, former House Speaker John Boehner told CNBC on Friday.
"It's their turn in the barrel," said Boehner, a Republican who had served for 24 years as a congressman from Ohio. "What Democrats are going through in 2016 and 2018, with the progressive movement, Republicans went through in 2010 and 2012 with the tea party movement."
The austerity-minded tea party, aimed at reducing the size of government, started after CNBC commentator Rick Santelli went on a tirade in February 2009, criticizing then-President Barack Obama's mortgage bailout plan. The rant came about a month before the financial crisis bottom in the stock market.
The staunchly conservative wing of the Republican Party, which has basically shed the tea party moniker but remains powerful to this day, targeted the more moderate Boehner in the months leading up to his abrupt resignation from Congress in 2015. He said at the time, "Prolonged leadership turmoil would do irreparable damage to the institution."
