I agree that the congress for a good part of the Clinton years was under Republican control.
But you must remember that Clinton refused to sign countless spending bills that lead to the shutdown of the government a number of times and over a number of years....
He kept the spending in line.
Bush II vetoed what two or three bills during his 8 years...the lowest number of vetos ever.
It certainly more complicated then what we have time for here.....
Bill Gross from PIMCO just published a great article on the grid lock/ falacy of a two party system.... the link is here
