Danger — Carlos Danger.

That’s the nom de plume that former congressman and current New York City mayoral hopeful Anthony Weiner used in lewd online exchanges with a woman named Sydney Leathers. She’s one of three strangers to whom, as he acknowledged Thursday, Weiner sent explicit messages after he was forced to resign from the House in 2011 for — sending explicit messages to random women. And Weiner said more women might emerge, noting, “I can’t tell you absolutely what someone else is going to consider inappropriate or not.” Um, no kidding.

Barraged by these latest revelations, Weiner ended his mayoral campaign, right? Ha! No way! At a surreal news conference Tuesday — one of the best/worst we have ever witnessed — Weiner and his wife, Huma Abedin, insisted that his behavior was in the past and that they were moving forward. “I am sure many of my opponents would like me to drop out of the race,” Weiner said. They would, of course, though common decency might suggest that, too.

Weiner began the week as a co-front-runner in the mayoral contest, along with City Council Speaker Christine Quinn. But, according to a Marist-NBC-Wall Street Journal poll released Thursday, he’s ending it in a downward spiral. Weiner is clinging to 16 percent of the vote, good enough for second place behind Quinn, but his favorability ratings have dropped more than 20 points since a similar survey conducted a month ago.

Even though Weiner isn’t in Washington anymore, he was all anyone in this town could talk about this past week. For that — and for ensuring that “Carlos Danger” will be in the political-junkie lexicon until, well, forever — Anthony Weiner, you had the worst week in Washington. Congrats, or something.
