Reply #5: This snip from her Wikipedia page indicates to me she's seems progressive:

Solis was able to obtain the support of the Los Angeles County Federation of Labor, Emily's List, Handgun Congrols, and the Sierra Club and the California League of Conservation voters, all of whom motivated a significant amount of volunteers and donors to help Solis win. Without a Republican in the race, Solis beat challengers from the Libertarian, Green, and Peace and Freedom parties to win with 79% of the popular vote in the general election. Solis was not without her own controversy, though, as her plan to lower the carpool restrictions on the El Monte Busway resulted in an uproar from bus riders and carpoolers that used the busway. The changes, which were implemented in January 2000, had not manifested themselves completely by the March 2000 election. Solis later voted in July to repeal portions of her own bill, effectively declaring it a failure.
