Pollster John Zogby reports in our weekly White House report card that the internet tapping scandal might build a new libertarian movement against the president.

"New polls just out show President Obama losing some of the public trust he once had. Overall public support is down a few points, once again into the high 40s -- the wrong side of a majority but nowhere near the numbers of really troubled presidents: Truman (23 percent), Nixon (23 percent), Carter (26 percent), George W. Bush (21 percent). Unemployment numbers tick as do employment numbers. And consumer confidence is gaining a little. The IRS has replaced Wall Street, oil companies, and pollsters on the bottom rung of the food chain. And revelations about the NSA knowing all, seeing all, and hearing all about all of us may just unite liberals, conservatives, libertarians, and socialists. This is the one to watch. So I downgrade the president this past week because events are getting ahead of him again."

This week's grade: D.
