The percentage [of Americans who identify themselves as Tea Party supporters] holding a favorable opinion of former President George W. Bush, at 57 percent, almost exactly matches the percentage in the general public that holds an unfavorable view of him.

Is the Tea Party movement really an uprising born from the election of Barack Obama? Not if the majority hold a favorable opinion of George W. Bush. As evidenced by their actions, both President Bush and President Obama believed in increasing the size and reach of federal government. Both Presidents pushed reckless financial policies that included increasing debt. Frankly, they have more in common than most Tea Party supporters would care to admit.
If those in the Tea Party really believed what their signs said, they would hold similar opinions of Obama and Bush. Very little separates the political principles of these two men and of most elected Republicans and Democrats. Another reason why real alternatives brought by the likes of Ron Paul are so refreshing.
