According to this article at the Washington Examiner, they did this with both of Bush's victories, too.
In 2000, 2004 and 2016, Democrats in Congress objected, tried to object, and generally disrupted the process of certifying the Electoral College vote. They did so with no substantive grounds, instead just for the political theater of it.
Twelve years ago, Democrats actually delayed the Electoral College certification. They got Sen. Barbara Boxer to object to Ohio's Electoral College vote. George W. Bush beat John Kerry by 120,000 votes in Ohio, but Democrats got their debate and their vote on the electors. House Democrats used the occasion mostly to attack Ken Blackwell, Ohio's secretary of state, who was a rising star in politics and — horror of horrors — a black conservative.So this is the new normal, it seems.
