They're almost breathless over there:
Two out of three Americans who watched President Barack Obama's health care reform speech Wednesday night favor his health care plans — a 14-point gain among speech-watchers, according to a CNN/Opinion Research Corporation national poll of people who tuned into Obama's address Wednesday night to a joint session of Congress.
But wait... there is this bit of cogent news about the poll:
The CNN/Opinion Research Corporation poll was conducted just before and just after the president's speech, with 427 adult Americans questioned by telephone. The survey's sampling error is plus or minus 5 percentage points.
The sample of speech-watchers in this poll was 45 percent Democratic and 18 percent Republican. Our best estimate of the number of Democrats in the voting age population as a whole indicates that the sample is about 8-10 points more Democratic than the population as a whole.
Which ought to completely invalidate the poll and make publishing it as news to be moot. But remember... this... is CNN.
