Nashua, New Hampshire

HILLARY Clinton is digging in for a tough fight against Senator Bernie Sanders of Vermont in next week's primary in New Hampshire, her advisers said on Tuesday, trying to spark political momentum and fundraising energy after only a razor-thin victory in the Iowa caucuses.

The Clinton campaign had considered shifting its focus to Nevada and South Carolina, which hold nominating contests later in February. But Mrs Clinton, with the strong support of former president Bill Clinton, decided that she would help herself more by closing the gap in New Hampshire, where polls show Mr Sanders with a double-digit lead. The Clintons even hope that she might pull off an upset win here, as she did in 2008, given their long history of campaigning in the state.
