As I’ve written before, there has been a shameful lack of outrage — particularly among Democrats and liberal commentators — over Obama’s stance that a U.S. president can kill American citizens with no due process, no transparency, and no accountability. If President George W. Bush had taken this stance in 2008, is there any doubt that candidate Obama would have opposed it?

But this isn’t just about Obama. Even if you trust his judgment and fidelity to the Constitution, Obama is setting a precedent for future leaders — perhaps a president you wouldn’t empower as judge, jury and executioner.

I tweeted shortly after midnight: “ATTN: Senators opposed to govt killing American in US (or even a wee bit curious abt modern warfare and Constitution) pls report to work.”

Meghan Coan, who described herself as a “big Obama supporter,” replied with a tweet chastising the president. “I’m actually afraid he’s not on the wrong side of history, that drones will be the norm and accountability taken out of war,” she said.

A voter from Virginia wanted to know whether the state’s Democratic senators Tim Kaine and Mark Warner were backing Paul. “If not,” she tweeted, “they won’t have my vote in the future.”

Meanwhile, Paul droned on. “What will the standard for how we kill Americans in America?” he asked at one point. “Could political dissent be part of the standard for drone strikes?”
