The political backdrop for Thursday's Supreme Court ruling on President Obama's health care law is vividly illustrated in the way rhetoric about the controversial measure has changed. The orange line indicates frequency of mentions for "Obamacare." The pink line is for "health reform."
In the graphic above, created by Capitol Words — Sunlight's tool for tracking the language used on the floor of Congress — you can see how the derogatory term "Obamacare," invented and mostly used by Republicans, as seen below. The red line indicates Republican mentions of the term, the blue, Democrats.
If winning a debate means defining the terms, it's interesting to see why the president has been on the defensive over the signature legislative achievement of his first term.
