That's the scoop from reporter Heath Haussamen.
Martinez hasn't said pubilcly that she's in, but Heath has several sources with knowledge of her plans to announce on Friday.
The entrance of Martinez, the district attorney in Dona Ana County, changes the race in several ways, adding another woman and another Republican to the mix.
Any one else who is serious about running has to announce pretty quick here, if they want time to fundraise, build their campaigns and travel around the state before the race. I'm partly kidding of course, but given the way the 2010 gubernatorial race is shaking out, I bet we're going to see the big name candidates emerge before the monsoons come.
