ROSEN: We all have reasons to fix our healthcare system, but Republicans in Congress keep voting to repeal Obamacare instead of fixing it. They would end protections for pre-existing conditions and let insurance companies charge people over 50 up to five times more than younger people. That's a disgrace. I'm Jackie Rosen, and in the Senate I'll work with both parties to fix Obamacare and bring down costs. I approve this message because we all have a stake in this.
