Ex-state Treasurer Kate Marshall said Monday she is mulling a political comeback as a candidate against Sen. Dean Heller in 2018.

"I'm evaluating the race," Marshall, a two-term Democratic constitutional officer and failed congressional hopeful told me via text message.

Marshall reportedly has the support of Sen. Catherine Cortez Masto, who has touted Marshall's chances against Heller, widely considered the most vulnerable GOP Senate incumbent next year.

Marshall is one of several potential Democratic candidates who could run against Heller, but she is considered more likely than some because of support from Cortez Masto and her eagerness to get back into the game.

I asked Marshall -- twice, in fact -- if she had met with Senate Minority Leader Chuck Schumer to talk about the contest.

"It's a comprehensive process, and I am still reviewing," Marshall told me, while dodging my question -- twice, in fact.

Others who are considered potentially serious about challenging Heller include Rep. Dina Titus, who has openly mulled a bid but would have to give up a safe seat, and Rep. Jacky Rosen, who is only a freshman but could consider a statewide race safer than her lean-GOP seat in an off year.
