His goal is trolling.
Trolling is a practice whereby a person takes a deliberately indefensible position simply to draw passionate excess from an opponent. That is Obama's goal here: He hopes for extreme language, impassioned opposition and eventually, impeachment.
This administration is hungry for impeachment. While no Republican leader in Congress has given even a smidgen of credibility to impeachment talk, the Obama administration has been fundraising off impeachment rumors. Last Friday, the White House said that it was not dismissing the possibility of a House impeachment; senior adviser Dan Pfeiffer said that Obama "would not discount the possibility." Two weeks ago, Obama brought up the possibility of impeachment in order to mock it to his supporters. As Politico noted, "Who's talking about impeachment? Barack Obama."
Joe Trippi, a Democratic consultant, explained why Democrats love impeachment talk: "The more they talk about it, the more it has a red hot effect on their base. So if you can get the temperature just right, you're turning out all your base voters, and Democrats don't take it seriously, and it's a good year for you. If that stove gets just a little too hot, and you lose control of it, you're going to have every Democrat on the planet turning out to stop it."
Obama trolls because he recognizes that trends cut against Democrats in 2014. If he believed that Democrats were well-positioned to win back the House of Representatives, he would threaten executive action and then call on Americans to give his party a majority. Instead, he seeks to gin up outrage on the right and enthusiasm on the left. And he'll use the lives of millions of Americans and non-Americans to do it. It's a desperation play, but it's his only play.
That's because Obama has no capacity for compromise. His strategy has always been simple: govern when you have a majority; campaign when you don't. And so, for the last several years, he's spent significantly more time doing fundraisers than being president -- and even when he's being president, he's simply setting up the next stop in his endless campaign.
