True, but by supporting abortion these Catholic politicians have renounced Jesus by their acts. The Church has the responsibility of telling them they need to repent or face the eternal consequences. Cardinal O'Malley has sounded the watchman's warning. It won't be he who will be held accountable for their blood.
I don't think they're listening, though...they've stored up too much vainglory for themselves to care. Besides most of them are lawyers so they probably figure they can repent at the last minute and failing that, argue their way into Paradise.
God is merciful, but He's not stupid.
For Jesus to say that it is better to kill yourself than be the cause of scandal is a very severe warning -- probably meaning the person will be condemned to hell...
