Why the heck does this need to be Federal law? Crime should generally be a State matter unless there is some interstate activity involved.
...or when it involves the mail or electronic communications generally understood to be federal concerns, military personnel or bases, federally0insured banks, or federal property or reservations. A letter, telegram, telephone call, or e-mail message involved in spouse abuse could be a federal offense. So would interstate travel to commit violence against an estranged spouse.
The federal system usually yields to state governments because state offenses are usually more severe than the federal offense. Prime example: many FBI cases involve "interstate flight to evade prosecution". The FBI gets relatively few convictions for that offense because interstate flight is usually not done for its own sake. So someone who committed an armed robbery in Michigan who gets caught by the FBI in California is likely to get convicted, if at all, for the armed robbery in Michigan and a 25-to-life term in Michigan which makes the federal charge of interstate flight a triviality.
I figure that a large number of the offenders in federal penitentiaries are for either mail fraud or wire fraud that can't be tied to a particular state.
...The 112th Congress is arguably the worst Congress in decades largely because of the extreme positions of the Republican majority in the House. My expectations are much the same for the 113th.
