Another Democrat shows his willful ignorance by accusing others of what they did.

Former top Obama adviser aims for GOP in tweet — delivers knockout blow to Obama & Pelosi instead

Dan Pfeiffer served in the Obama White House until 2015, first as the White House communications director and then as a senior adviser to former President Barack Obama, so he knows a thing or two about how politics in Washington works.

But when the former White House staffer tried to offer legislative wisdom on Twitter Saturday, things didn’t quite go as planned.

“General rule of politics: If you have to rush to pass your bill before people find out what is in it, you will regret passing that bill,” Pfeiffer tweeted.

Not only was the passage of Obamacare partisan and rushed, but then-House Speaker Nancy Pelosi (D-Calif.) wanted it to be passed before it was read.

“We have to pass the bill so that you can find out what is in it,” Pelosi infamously saidduring a conference in 2010.

It leaves many to question whether the law would have passed if it would have been read by the lawmakers who voted for it, given the extreme consequences it has had on the American marketplace.

Needless to say, Twitter slammed Pfeiffer for missing the irony of his tweet:
