The next most partisan divide at the end of the first 100 days in office was registered by Bush, with a 51-point partisan divide caused by the sharp difference in strong approval expressed by Republicans (87 percent) and much lower approval from Democrats (36 percent).
Interestingly, President Bush at the end of the first 100 days in office had an 11 percent higher rating from voters of the competing party than Obama enjoys this year.
Bush's average approval ratings remained strong throughout his first term (62.2 percent), dropping only in his second term (36.5 percent).
A lesson from Bush that Obama should study is that sharp partisan differences can over time lead to decreasing overall approval rates.
President Bush was dogged in his second term by the continuing war in Iraq and Afghanistan, as well as an economy that began declining in 2007, after the mortgage bubble burst.
Obama may well expand the war in Afghanistan, and the economic recession that began officially last December appears resistant to any quick recovery, despite administration's determination to continue bailouts, to expand the involvement of government in the management of the economy and to fund an unprecedented growth in the social welfare state with trillions of dollars in federal budget deficits..
