Consider this - a Congressman writes the laws for our nation, and decides where our tax money will go. The most deangerous thing that any Congressman can do is put himself in a position where he could be blackmailed. Blackmailed into betraying his constituents, or his country.
What Mr Weiner did placed every one of us at risk. If anyone in receipt of those emails and pix were to say to Weiner, "I'll take these to the press unless you vote this way or that," just what do you think he would do? Bear in mind - the ONLY reason he admitted his guilt today is because more - and worse - pictures showed up, and he had no choice but to confess.
Then there is the matter of JUDGEMENT. Anyone who judgement is so atrocious that he would do something this stupid - and do it multiple times - does not have the judgement necessary to help lead our nation, write our laws or spend our money.
Mr. Weiner - do the honorable thing - resign quietly.
