The campaign of Maryland Del. Heather R. Mizeur, who is gearing up for a 2014 gubernatorial bid, on Wednesday sought to recruit supporters by advertising that she would be the first openly gay governor elected in the country.

The pitch was part of an e-mail solicitation sent out by Mizeur’s campaign manager, Joanna Belanger, that sought contact information from people willing to “stand with Heather.”

“Heather is the best person to lead Maryland,” the e-mail said. “And if elected, she would also be the first openly LGBT Governor elected in the country — a big step forward. As we celebrate Gay Pride month, we ask our friends and allies to PROUDLY stand with Heather.”

Mizeur (D-Montgomery) has yet to formally announce she’s running for governor, but she has been criss-crossing the state, seeking to build support.

If she moves forward with a gubernatorial bid, she will face at least two better-known and better-funded Democratic rivals: Lt. Gov. Anthony G. Brown (D), who announced his candidacy last month; and Attorney General Douglas F. Gansler (D), who is expected to make his bid official this fall.

Rep. C.A. Dutch Ruppersberger (D-Md.) is also considering joining the Democratic primary to succeed Gov. Martin O’Malley (D), who is term-limited.

Belanger’s e-mail acknowledges some of the obstacles Mizeur will face.

“We will not have the biggest war chest, and we won’t rely on establishment and insider endorsements,” it said. “What sets us apart from the rest of the pack is our growing grassroots network — people just like you who have chipped in a few dollars, liked us on Facebook or volunteered to help the campaign as we continue to build momentum.”
