NEW BEDFORD — The city is about to be at the center of the presidential primary season just at the last minute possible.

Sources close to the Clinton campaign say former President Bill Clinton will visit New Bedford Tuesday as Hillary Clinton tries to add Massachusetts to her Super Tuesday victories. The former president will speak at 12:05 p.m. in front of the Buttonwood Park Warming House on the Lake and Oneida streets side.

"I look forward to President Clinton's encore performance in New Bedford," said Mayor Jon Mitchell who has endorsed Hillary Clinton and worked to open a Clinton headquarters in the downtown.

The former president drew a huge crowd a few years ago, Mitchell said. "I look forward to seeing him here tomorrow in support of his wife's candidacy."

Clinton spoke in Custom House Square in 2002 on behalf of former Treasurer Shannon O'Brien's unsuccessful campaign for governor.

Polls show Hillary Clinton is leading Vermont Sen. Bernie Sanders in most of the 10 states that are voting Tuesday but Massachusetts is thought to be more competitive than most. Both Hillary and Sanders campaigned in Massachusetts Monday.
