Since WW2 the GOP has never achieved this.
Team Donkey has achieved it 3 times: early in FDR's time, under LBJ, and for the first 1.5 years of Obama, until Ted Kennedy died and was replace by GOP Senator Scott Brown.
When you look at the legislation that has transformed America, is blatently unconstitutional, and is bankrupting us these three periods stand out. FDR and the New Deal, LBJ and the Great Society and Obama and Obamacare.
It is interesting to speculate on whether, if the GOP actually scored the trifecta they would know what to do with it. For instance, cleaning out the illegal mess, despite the inevitable whining of the media.
One suspects they would not.
Given the record they have for inaction [and wrong action], I would expect nothing good from such a setup.
They’d know what to do with it; problem is, it won’t be the right thing for the country and would be too like their Democratic Unipartiers.
Republicans had this - with Bush early in his first term. What did HE do with it? Yes he did a superb job in addressing GWOT, but it also got us TSA, DHS, Patriot Act and FISA court that NSA, DHS, CIA, FBI and everybody and their brother are using to spy on US Citizens while they call Islamic Terrorist actions "random violence" and kiss CAIR's camel butt.
