From Wonkblog:
According to the nonpartisan [Kaiser Family Foundation]’s June tracking poll, support for the health law among Democrats jumps dramatically when labeled “Obamacare,” vs. the plain old “health reform law” language some of us old school media types prefer. . . .
According to the poll, overall favorability of the law jumps from 35 percent to 42 percent when the term “Obamacare” is used. That’s almost entirely due to the enthusiastic reception it gets from Democrats, 58 percent of whom responded favorably to “health reform law,” compared with 73 percent for “Obamacare.”
Independents in the poll reacted about the same to both descriptors (about a third responded favorably while around a half responded unfavorably). Among Republicans, 76 percent responded unfavorably to “the health reform law.” That number jumped to 86 percent when “Obamacare” was used.
