I'm not so sure.
Click thru and read the article. Addison Gardner sounds like a disillusioned non-partisan "moderate". He's disappointed in the Democrats...but he hates Republicans.
I didn’t get that impression but you might be right.
It might have something to do with this unavoidable fact:
“When he [Bush] took office in January 2001, President Bush inherited a national debt of $5.7 trillion. When he left office, America’s debt was nudging $10 trillion, and less than $1 trillion was spent terminating terrorists abroad.”
Maybe he just dislikes big-spending Bush Republicans who are pretty much indistinguishable from, say, Democrats??
