Because of your glee for her introduction of the bill. If you are ok with her getting rich(er] from stocks while in Congress, but are just now supporting the bill, then that also makes you a hypocrite, which we already knew. Do you also deny that you think she's doing it for the good of the people or is it politically motivated?
Bipartisan, huh? We'll see, won't we, when the bill hits the Senate. And, be that as it may, why didn't Republicans introduce the bill last year, when they controlled everything?
There you go. This is the angle. She moves against her past stance to get the Republicans to shoot down the bill. Then she can say "look what the evil money loving Republicans are doing" Things are not looking fabulous for the Dems right now. At this point in the game, you have to force your opponent to make a stance and then react to it. Republicans are playing a game of their own with these censures. This will hurt them. There could be a double win here.
You have a very strange (read that: fallacious) notion of hypocrisy. Here, let me give you an allegory: The Saints are in the Super Bowl with the ball at their own 20 yard line, down by two with only 5 seconds remaining. So, Max Saintly, their mighty armed QB, heaves a pass down the sideline as far as he can throw it, 65 yards in the air. Lo and behold, the referee on that side of the field calls pass interference on the Rams. First and 10, Saints, on the Rams' 15 yard line, one more play to go because the game can't end on a defensive penalty. The Saints line up and kick a winning field goal. Game over. Saints win, Rams lose. The country is outraged. The Rams were beaten on what 90% of the country thinks is a rotten rule, i.e. pass interference penalized at the spot of the foul. Nancy Pelosi, general manager of the Saints, actually agrees with them. "We benefited under an old rule that was not of my making. But this is a bad rule. We need to change this rule. No team should be able to gain 65 yards in that way." Winston, hearing that Nancy wants a rule change, screams "Nancy's a hypocrite!" Moral of the story, in case you missed it: the Winston of the allegory makes no more sense than the Winston1 of this thread.
