The three Democratic presidential candidates will participate in an Iowa town hall next Monday, exactly one week before the highly anticipated Iowa caucuses.

CNN anchor Chris Cuomo will moderate the prime time event, which will take place at Drake University in Des Moines. During the town hall, Democrats in the state will be allowed to question the candidates -- former Secretary of State Hillary Clinton, former Maryland Gov. Martin O'Malley and Sen. Bernie Sanders -- about their positions and platforms.

"We are honored to partner with CNN on their town hall with our three fantastic Democratic candidates," said Dr. Andy McGuire, chair of the Iowa Democratic Party. "With this event airing just one week before the first-in-the-nation Iowa caucuses, it's an incredible opportunity for Iowans to see our candidates detail their plans to move our country forward and their vision for Iowa and the nation."

The town hall will air Monday, Jan. 25 from 9 p.m. to 11 p.m. EST.

The announcement comes just after a new CNN/WMUR poll found that Sanders' lead in New Hampshire has stretched to nearly 30 points. According to the survey, which was conducted before Sunday night's debate and released Monday, 60 percent of voters support the Vermont senator while 33 percent are standing behind the former first lady. That gives Sanders a commanding 27-point lead in the crucial early voting state.

The self-proclaimed Democratic socialist has seen his support in the state increase by 10 points since a late-November/early December CNN/WMUR poll found him at 50 percent compared to Clinton, who received 40 percent.

The new survey also shows that the majority of New Hampshire Democrats have definitely decided who they will support in the primary race. Back in early December, 36 percent had finalized their decision, while 52 percent said they are sure about their choice now.
