Simply said....
Reagan's policies like deficit financing, tax cuts, the Star Wars stuff, really fucked up the United States' Government and Economy. The Neo-Conservative movement started the ball rolling. Dimson is basically carrying only a half-gallon bucket of Reagan's water (policies) to the present day...
The Iran-Contra mess makes Clinton's Monica affair look like child's play...However Reagan wasn't that bad compared to that IDIOT presently sitting in the White House. (After all Ray-gun was legitimately elected unlike Dimson)
The good news is that the kids out of Reagan's OWN loins, both Ron Jr and Patti are both LIBERALS unlike their father. Even Nancy has come around and opposed Bush on stem cell research for Alzheimer's.....
