"Hillary Clinton lost, but Republicans still want to investigate her" infers that the desire to investigate a political candidate is based on the desire to win elections rather than a desire to see justice done.  Perhaps that is true,  particularly in the Democrat DA prosecutions of Tom DeLay, Rick Perry and Scott Walker.  What if the Republicans are disgusted with the probably felonious actions of HRC rather than angling to win another election?  What if they are revolted by Obstruction of Justice (deletion of 30,000+ emails under subpoena), Corruption (Bubba gets paid millions for speeches by companies and nations who need HRC approval for business deals),  and violations of the Espionage Act (18 USC 793 (f)) for gross negligence in the handling of Defense Information by putting hundreds of emails on home brew servers.
