These days there seems to be an increasing number of calls to impeach President Obama. “Enough is enough of the years of abuse from this president,” wrote former vice presidential candidate Sarah Palin in Breitbart News on Tuesday. “It’s time to impeach.” National Review’s Andrew McCarthy is promoting a new book entitled Faithless Execution: Building the Political Case for Obama’s Impeachment. In February, the House Judiciary Committee held a hearing on “Enforcing the President’s Constitutional Duty to Faithfully Execute the Laws,” during which the topic of impeachment came up a number of times. A few Republican lawmakers have discussed the subject publicly.

Given the growing crisis on the southwestern border, in large part the result of Obama’s executive actions and inactions, it’s likely such calls will continue, and perhaps increase. Which makes this a good time to remember the last time there were growing calls to impeach the president — in 2006, when Democrats worked themselves into a frenzy over the contemplated impeachment of George W. Bush.
