I don't get why the GOP should even bother with NH-01. Even if Shea-Porter were vulnerable (and she isn't), the Republican would either be guaranteed to be a one-termer or a liberal "RINO". Same is true for Annie Kuster's district.
NH-02 is Safe D and NH-01 is Likely D IMO. The GOP should focus on defending Poliquin and maybe finding a decent candidate to run against King rather than wasting time and money in NH.
Hell, the GOP is going to be needing to spend tons of money to save Darrell Issa's seat.
