U.S. Sen. Cory Booker of New Jersey has formally launched his re-election campaign with the first of a series of kick-off events.
A poll last month showed the incumbent Democrat may have a tighter race than observers expected. The Quinnipiac Poll showed Booker was ahead of little-known Republican Jeff Bell by 10 percentage points.
Booker told supporters at Camden County College on Wednesday that he is working with Republicans and Democrats on a variety of issues, including the cost of college and federal funding for programs for veterans with traumatic brain injuries.
He portrayed Bell as unwilling to work with Democrats.
Booker gained the endorsement of several environmental groups on the weekend.
The former Newark mayor was elected last year to serve the remainder of late Sen. Frank Lautenberg’s term.
