The Roe Effect isn't as strong as the War on Poverty effect (free food, housing and medical care for able-bodied pre-retirement indigent individuals). Roe merely gave intelligent women who were otherwise conscientious the ability to abort their babies on demand, thereby depriving us of the higher IQ and moderate Democrats. The War on Poverty effect gave us an explosion of new babies by the low IQ indigent (e.g. Octomom) for whom popping out babies is how they make a living. Bottom line is that welfare is giving us a more liberal and stupid (as in naturally unable to learn) population that used to be offset somewhat by unwanted babies from the smarter elements of society. If abortion had been legal when Steve Jobs was conceived by his two grad student parents, he would have been aborted. Bottom line is that both Roe and the War on Poverty have been a disaster for conservatives, Roe because it has deprived this country of an uncountable number of highly-productive people like Jobs.
Additionally, anyone who believes Obama has 243 reliable EVs is going to have some splaining to do when gets less than 243 EVs in December.
The current electorate was born at least 18 years ago, back when white births were the majority of all live births in the country. Thanks to birthright citizenship, 18 years from now, Democrats will have a lock on the presidency. And in a decade, it wouldn't surprise me if Texas became reliably Democratic. John Derbyshire was right. We are doomed...
Just like all the early 20th century Italian and other Roman Catholic immigration meant the death of the GOP as we all know Italians will vote Dim for ever.
You probably also agree with Al Gore that a 1 degree temperature this year implies that average temperatures will be 20 degrees higher in 20 years, right? Well I have news for you straight line extrapolation does not work well for predicting the future.
