Steve Chapman has an excellent article up at Reason on where the Bush 43 years have gone wrong.
Here’s two very telling issues:
The Budget. Bush represented the alleged party of small government, yet under him, federal outlays exploded. During his presidency, spending was up by 70 percent, more than double the increase under Bill Clinton. When Bush arrived, the federal government was running surpluses. Since then—not counting the horrendously expensive financial bailout—the national debt has nearly doubled. You can’t blame Congress for all this: Bush was the first president in 176 years to go an entire term without vetoing a single piece of legislation.
Executive power. Conservatives are supposed to believe in strict limits on government power, but Bush pushed incessantly to expand the prerogatives of the president. He asserted the right to ignore laws banning torture and restricting wiretapping. The Supreme Court found that his imprisonment of captives at Guantanamo Bay violated the Constitution by denying them the right to challenge their detention in court.
