Democrats have been in power for so long that they’ve forgotten how to oppose. Their party has been on a roll since 2005 when the botched Social Security reform, the slow bleed of the Iraq war, and Hurricane Katrina sent the Bush administration into a tailspin. The Democrats won the Congress the following year and the White House two years after that. And while they lost the House in 2010 and the Senate in 2014, Democrats still had the advantage of retaining the White House, a president seemingly immune from criticism, the courts, the bureaucracy, and large portions of the media. The correlation of forces in Washington has weighed heavily in favor of the Democrats for a decade.
