Senator Ron Johnson, reputedly the dumbest member of the world's worst debating society, decided to say the quiet part out loud. He casually proposed Social Security, Medicare and Veterans' benefits be approved by Congress on an annual basis instead of their present status of paid for entitlements. Coming from Johnson, many commenters laughed the proposal off as they would if another brain dead Republican,(Tommy Tuberville, can you hear me), touted this as a realistic policy alternative.
However, if you look at the GOP and its battle against so called "entitlements" for the last 100 years, this is just the first salvo in a new attack. As the recent vote in Kansas shows, Republicans badly overplayed their hand in the recent Supreme court decision gutting Roe vs. Wade. There is very little public support for destroying SS and Medicare, but making it part of the larger culture wars, Johnson, et.al. think they can help the 30% of the population who listen to them come to the decision they should destroy their futures in the name of denying benefits to "those people".
