Not much since Eisenhower. They did let the AWB sunset, but that wasn't pro-active. All else has been pretty much ineffective or smoke and mirrors.
Much of what they have done has had such glaring opportunities for abuse, yet people were roundly howled at for opposing those measures (like the Patriot Act).
People need to always look at such measures and imagine what their worst enemies would do with that power, unchecked, and then act/vote accordingly.
So much got through because people thought it would be used for "good"...and has since been turned on us.
I think the rot really began to take hold with the 16th Amendment (income tax) followed by the 17th Amendment (direct popular voting for senators).
Couple those two acts and along comes Woodrow Wilson becoming president and so the Republic was speeding along the path to rampant progressivism.
