Now that Republicans have swept Democrats completely out of power in Congress, will President Obama still go through with his long-promised executive order to legalize a sizable chunk of the nation's undocumented immigrants?

GOP leaders are warning him not to in the starkest of terms. "When you play with matches, you take the risk of burning yourself. And he’s going to burn himself if he continues to go down this path," Speaker John Boehner told reporters in the Capitol on Thursday, in his first press conference since the election. The speaker said a unilateral move by the president after the voters rebuked him on Tuesday would "poison the well" with Republicans, and "there will be no chance of immigration reform moving in this Congress. It’s as simple as that."

A day earlier, incoming Senate Majority Leader Mitch McConnell said much the same thing, equating executive action on immigration to "waving a red flag in front of a bull."

It's a lot of sound and fury, but it probably won't change the mind of a president who has been waiting for House Republicans to act on immigration reform for nearly two years. Boehner can't do any less on the issue than he's already done, and few in Washington gave much chance to an overhaul passing under Republican rule in 2015 anyway.
