First Lady Michelle Obama is scheduled to visit Stamford on Monday in a show of support for Attorney General Richard Blumenthal in his race for the U.S. Senate, the Blumenthal campaign has confirmed.

Obama will attend a function for Blumenthal at The Palace, Stamford Center for the Arts, in downtown Stamford. It will be the second time during the campaign a member of the first family has stumped for Blumenthal. President Barack Obama came to Stamford to raise funds for the Democratic candidate last month.

Blumenthal is running against Republican Linda McMahon. Polls show that McMahon is closing in on the attorney general, who once commanded a decisive lead. The most recent Quinnipiac University Poll showed Blumenthal with a mere three-point lead over McMahon, 49 percent to 46 percent.

Blumenthal isn’t the only candidate warranting an Obama appearance. The First Lady is traveling throughout the U.S. in support of Democratic candidates, whose success at the polls next month is considered crucial for the president to move his agenda forward.
