The following is from Political Wire:
Nielsen reviews viewership data from the national political conventions and draws several interesting conclusions:
Nearly two thirds of all U.S. households (64.5% or 73.2 million homes) tuned into at least one of the 2008 political conventions. This is about 120.1 million people. Viewership levels for the two conventions were essentially tied, with about half of all households watching each one.
15.0% of all households tuned to just the RNC, and 15.7% tuned to just the DNC. Another 33.9% of all households tuned to both conventions.
Homes that watched both conventions were more likely to be headed by someone 65 years or older. They also completed the most formal education: nearly one-third (32.3%) graduated from college. Those watching only one convention were fairly comparable on both education and HOH age, within a point or two.
Homes that only tuned to the RNC were more likely to have higher incomes ($100K+), to have a larger household size (4+), to be white, to own a DVR, and to have a head of household with higher education (4+ yrs college) and aged 35-54.
Homes that only tuned in to the DNC were more likely to have a lower income (<20K), to have a smaller household size (2), to be African American, and to have a head of household who is younger (<35) and who has less education (1-3 Yrs College).
So the "higher income" folks were more likely to watch the GOP Convention, eh?
They were probably laughing it up while McCain promised them more, more, more.
