The most potentially influential politician you've probably never heard of, former two-term Maine Gov. Angus King, on Tuesday officially entered the race to replace retiring moderate GOP Sen. Olympia Snowe.
King, 68, an alternative-energy entrepreneur and supporter of President Obama, filed more than 6,000 signatures with Maine's secretary of state to ensure his place on November's ballot.
He'll run as an independent, as he did for his successful gubernatorial runs in the 1990s.
Congress is considering legislation allowing the government to search through Internet traffic for early warnings of cyberattacks. The bills are controversial — worries about government surveillance have led to protests online.

It's a great honor to help another person, but it comes at a cost for me.
