Congressman's Woman -- Big Weiner Supporter

40-year-old Lisa Weiss -- a Nevada blackjack dealer who went back and forth with Weiner on Facebook for more than a year -- tells TMZ she first began messaging him in August, 2010, after hearing an

he gave on health care.

Weiss sought Weiner out, messaging him, "You are the coolest dem on the planet!" She added, "Keep fighting for the sane people in this country!"

Weiner wrote back, "Thank you Lisa. Glad you have my back. You keeping an eye on the wackadoodle Angle for us." Sharron Angle is a guns rights advocate who ran for Congress in Nevada.

Weiss tells us she's a liberal democrat who believes in Weiner's policies and spent a lot of time messaging him about his views. She believes it's unfair to target Weiner: "Bill Clilnton was the best President we ever had and look what he did. Kennedy banged everything in sight."

As for using Congressional resources to carry on their sexual conversations, Weiss says the only time she talked to Weiner from his office was one night at around midnight, when he talked with her on the phone for 30 minutes and it was "strictly about politics." She says she was actually surprised the conversation didn't get sexual."

Weiss, who says she wants to apologize to Weiner's wife, does admit the conversations got raunchy. One notable mention: In February, after watching Weiner on Bill Maher's show, Weiss wrote, "Didn't think I could love you more until I saw you on Bill Maher tonight."

Weiner responded: "Maybe Maher will let me do you on his desk. Since u like me there."

And we had to mention the cheesiest line of all. Weiss said in one message, "didn't want you to call homeland security on me." Weiner responded, "No, we have a special secret agency that deals with hot women."
