Well, let's see. Reagan raised taxes 11 times and he raised the deficit to an all time high. Reagan turned our status from a creditor nation to a debtor nation. Remember Iran-Contra during Reagan's reign and the wholesale firing of the air traffic controllers and the declaration that ketchup is a vegetable? Reagan did not ever submit a balanced budget; the highest unemployment rate during his terms was 9.8% and stayed that way for a few years. Trickle-down? How'd that work for you?
Then there is G.W. Bush: How about the tax cuts for the wealthy, the invasion of Iraq and Afghanistan in a nonsensical war ("Mission Accomplished"), the screwing with the Constitution under Bush by stripping liberties, warrantless wiretapping, invasion of privacy. The Bush administration kept us safe except for 9/11, Katrina's wipeout of New Orleans was a shining example of Republican help ("Brownie, you're doin' a heck of a job!"). Bin Laden is still around ("We're going to hunt him down like a dog.")
The Repugs promise everything under the sun but never deliver. There hasn't been anything they've actually accomplished in the last 30 years that they can point to as having been really good for the middle, working class of this nation.
Why go on? Repugs accomplishments: 0, nada, nothing, zero, bubkes.
