Democratic U.S. Sen. Kirsten Gillibrand's bid for another term has received some early support as she gears up for a re-election contest next year. 

The backing in the form of early endorsements and appearances at fundraisers comes as, so far, Gillibrand has drawn only a handful of potential Democratic primary opponents. 

Gillibrand is sitting on more than $6 million in cash on hand for her re-election bid, according to the most recent campaign finance data. She was first appointed to the seat back in 2009 by then-Gov. David Paterson after Hillary Clinton was nominated to become secretary of state in the Obama administration. 

Last month, Gillibrand received an early endorsement from the Westchester County Democrats. In a statement, party Chairwoman Suzanne Berger pointed to Gillibrand's efforts on gun measures as well as support for first responders with Sept. 11-related illnesses. 

“Last term, Senator Gillibrand secured a number of huge wins for New York; she passed federal anti-gun trafficking legislation, a bill to give millions of veterans health coverage for toxic exposure and secured $1 billion for the 9/11 health program," Berger said. "Senator Gillibrand delivers and we’re honored to support her.”

Gillibrand is also making stops on the Democratic fundraising circuit. She's appearing with her fellow statewide elected officials on July 31 at a fundraiser for the Brooklyn Democratic Committee, where tickets range between $5,000 and $50,000. 

And in August, Gillibrand is set to appear at a fundraiser in Lake George for the Democratic Rural Conference, where donations can run between $250 for individuals and $5,000 for a "platinum" sponsorship. The Democratic Rural Conference is a key organization for the party outside of New York City and suburban counties. 

For now, her declared Democratic primary opponents include Army veteran Will Schweitzer and Khaled Salem. 

Former Rep. Lee Zeldin, who ran for governor last year, has not ruled out a bid for Senate on the Republican line.
