I won't give glowing praise for Democrats and a complete dismissal of Republicans on health care throughout the last century, because Democrats were only slightly better than Republicans when it came to fixing the complete mess our health care financing system has become.
But this isn't about history, it's about now. It's about the choices voters will face next week, and for at least the next several election cycles. Once again; we don't have a buffet of choices each election, despite your idealism. We have two choices in pretty much all races; a Democrat and a Republican. And right now, Democrats have taken steps to fix the health care financing system, and the Republican Party blocks them every step of the way and protects the status quo.
Two and a half years ago, Congress passed a historic reform of our health insurance system, called the Affordable Care Act (ACA). Every vote for passage of this bill came from a Democrat; not one Republican voted for it. This is not an indication of the bill's flaws, but rather an absolute statement that Republicans have no intention of supporting any health insurance reform. They added hundreds of amendments to the bill, and never had an intention of ever supporting it.
