WASHINGTON (CNN) -- Sen. Barack Obama, D-Illinois, will have key Granite State Democrats all to himself December 10 when he appears at the state party's election victory celebration.

The freshman senator was the only potential White House hopeful invited to the event.

"We are honored that Senator Obama has accepted our invitation to celebrate the historic, tidal wave victory New Hampshire's Democrats experienced this November," State Party Chair Kathy Sullivan said in a statement.

Sullivan invited Obama after the senator called her to congratulate New Hampshire Democrats on their midterm election victories.

Obama -- who has acknowledged he is considering a run for president -- quickly accepted Sullivan's invitation, according to New Hampshire Democratic Party spokeswoman Kathleen Strand.

According to Strand, because Obama accepted the invitation, no other White House hopefuls were invited to the celebratory event.

Obama has said he will make an announcement on his political future early next year.
