WASHINGTON (CNN) -- The first-in-the-nation New Hampshire presidential primary is over a year away but two potential presidential aspirants will trek through the Granite State this weekend as they consider waging presidential bids.

New Mexico Democratic Gov. Bill Richardson heads there Saturday to deliver a speech in front of the Democratic State Party Committee in Manchester. The State party specifically invited Richardson to join their celebration of Gov. John Lynch's re-election. Richardson is also slated to attend three meet-and-greets with Granite State Democrats in Hillsborough, Gilsum, and Hooksett.

Richardson, who also plans a private meeting with Lynch, is the outgoing chairman of the Democratic Governor's Association.

Sen. Joe Biden, D-Delaware, will also venture to the key-campaign state this weekend, slated to deliver remarks at the World Affairs Council of New Hampshire in Manchester on Sunday. Biden also plans to meet with party activists in Concord and Hopkinton.

Richardson has said he will formally decide on a presidential run after the new year. Biden, who has long said he plans to run for president, has yet to make an official announcement or file formally with the Federal Election Commission.
