The Tea Party - how frightening is this movement?

[Scruff7]

With reference to the below graph,

Area A indicates GDP between 1988 and 1990, doesn't this show a reletive reduction in GDP increase for the period? perhaps indicating a slowdown in the economy? Hense the gradual reduction in year over year growth from 1989 to 1990, resulting in stagnation in 1991.

Area B appears to show the greatest gradient, indicating the highest increase year over year in GDP and therefore a strengthening of the economy. More jobs, better wages, more money to take home.

Area C appears to show something has gone really quite wrong. A reduction in GDP mirroring the drastic reduction in elec and overall energy consuption, which could indicate a massive slowdown in industry (the largest user of power). There's strong growth following this though (although not as strong as the 1996 to 2000 period), correlating with the global financial growth that occured up until the 2008 financial collapse.

Being from the UK, I don't really know why this has happened in the US, but from my basic political understanding, Area B represents Bill Clintons Democratic presidency, Area C the early years of George W Bush?
