By that matter, you can say virtually none of the Senators have done that with respect to shrinking the size of government (under the “leadership” of McConnell, who is absolutely as useless as Boehner in the House). Wolf could only make promises, but promises are worthless during the election season (they always seem to find religion before November and go right back to the devil come January).
There needs to be drastic changes made, regardless. But that will have to start by tossing leadership and replacing them with people committed to change and shrinking the government. All those in leadership are really only interested in power and how to preserve it.
Roberts has a history, Wolf does not - Wold may or may not have turned out to be an American I do not think Roberts is much of an American. That does not make him a bad person, just someone who should not be in the Senate
