Story highlights Longtime New Hampshire Democratic activist Dudley Dudley told CNN Friday that she has decided to endorse Bernie Sanders for the Democratic 2016 nomination.

Her decision comes less than two months after she hosted former Maryland Gov. Martin O'Malley at both her Durham, New Hampshire homes.

Wolfeboro, New Hampshire (CNN) Sen. Bernie Sanders has snagged a key endorsement in New Hampshire that may sting a little for Martin O'Malley's campaign.

Longtime New Hampshire Democratic activist Dudley Dudley told CNN Friday that she has decided to endorse Bernie Sanders for the Democratic 2016 nomination. Her decision comes less than two months after she hosted O'Malley at both her Durham, New Hampshire homes.

Since then, according to a recent CNN/WMUR New Hampshire primary poll , frontrunner Hillary Clinton's lead over Sanders has shrunk from 38 percentage points to 8, with O'Malley trailing both. Likely Democratic primary voters are now more apt to see Sanders as the candidate who "best represents the values of Democrats like yourself," the poll found.

Sanders recently finished a two-day swing through the state that saw 500-person crowds and high attendance at more intimate house parties.

Dudley told CNN she was won over by Sanders focus on money in politics, but was particularly impressed by his style of delivering his message.
