I remember after President Reagan was shot, Secretary of State Alexander Haig said something along the lines of “I’m in charge here.” Technically, he was referring to the White House itself, not the office of the Presidency. VP Bush was not there, and Reagan was at the hospital. Despite all the Left’s loony accusations, Haig wasn’t really trying to circumvent the Constitutional line of succession.
But now that Obama is on vacation, it appears that Joe Biden has decided to fill that power void at the top. I wait for the Left to accuse Biden of trying to subvert the Constitution. For the record, I am not suggesting that Biden is trying to seize the Presidency. I just think he’s a blowhard.
