Palin opened the column with an anguished note about the crisis on the border.
"His unsecured border crisis is the last straw that makes the battered wife say, 'no mas,'" she wrote.
After detailing Obama's "years of abuse," Palin not only called for impeachment, but said that politicians who oppose such action should pay a price.
It’s time to impeach; and on behalf of American workers and legal immigrants of all backgrounds, we should vehemently oppose any politician on the left or right who would hesitate in voting for articles of impeachment.
The many impeachable offenses of Barack Obama can no longer be ignored. If after all this he’s not impeachable, then no one is.
Conservative calls for impeachment were bound to gain traction after House Speaker John Boehner (R-OH) announced his intentions last month to sue the Obama administration over its use of executive actions.
Boehner, for his part, said at the time that his lawsuit is "not about impeachment"
Sen. John McCain (R-AZ) told reporters in the Capitol on Tuesday afternoon he hadn't read Palin's op-ed on Breitbart, but he said he will.
"I respect everybody's opinion," McCain said of his former 2008 running mate. "Honestly, I'd have to read her rationale for it before I can make a judgment. But am I proposing that the President be impeached? No."
