Former Massachusetts senator Scott Brown (R), who is considering a Senate run in New Hampshire in 2014, is out with a new op-ed that suggests he's getting closer to running in the Granite State.

In the op-ed, Brown focuses on the effects of the federal health-care law in New Hampshire -- not Massachusetts, notably -- and appears to take a shot at his would-be opponent, Sen. Jeanne Shaheen (D-N.H.).

"Many other Americans are experiencing fewer medical options as insurers restrict their choice of doctors and hospitals in order to keep costs low," Brown writes, adding: "For example, in New Hampshire, only 16 of the state’s 26 hospitals are available on the federal exchange, meaning patients must either pay more to keep their current doctor or seek inferior care elsewhere."
