There now are two official candidates for the Republican nomination in New Mexico’s 2010 race for governor — and that field appears likely to grow over the next few weeks.

The latest entry is state Rep. Janice Arnold-Jones, who had been exploring the race for months. Arnold-Jones on July 26 sent a letter to supporters launching her run for the seat of term-limited Democratic incumbent Bill Richardson.

An official announcement is scheduled to come sometime later in August, according to local political blogger Heath Haussamen.
