What does a firearm have to do with alcohol and tobacco?
I did a quick Google, and -- sure enough! --

And I'm also pretty sure it's not "Republican" DAs and AGs refusing to prosecute crime.
"At the N.R.A.’s instigation, Congress has limited the bureau’s budget. It has imposed crippling restrictions on the collection and use of gun-ownership data, including a ban on requiring basic inventories of weapons from gun dealers. It has limited unannounced inspections of gun dealers. Fifteen years ago, the N.R.A. successfully lobbied to make the director’s appointment subject to Senate confirmation — and has subsequently helped block all but one nominee from taking office."
I'm pretty sure no DA is refusing to prosecute violent crime. One party is limiting the gun crimes that DAs can prosecute. https://www.salon.com/2022/06/06/us-laws-are-causing-mayhem-...
How would it help at all? They've already proven willing to break the law with the straw purchase.
> All of these would stop repeat offenders, and if I recall, the majority of straw sales are repeat offenders knowing they don't get in much or any trouble buying guns this way.
You don't know what you're talking about. It's a felony, and precludes you from purchasing or even possessing a firearm ever again. It's not possible to be a repeat offender.
