That's a bit of a stretch. There's a difference between a line here or there and a fleshed out policy position.Every Republican candidate since Nixon have supported repealing it. They just never do it.
Once upon a time the 14th amendment took some flack after it incidentally allowed for application of the bill of rights to the States. Integration of the States into the Federal rights system is broadly supported by everyone now. In fact, I suspect that most people would be surprised if they looked at pre Miranda State laws.There are a number of amendments that the Republicans seem to have a particular problem with. The ones I've heard them particularly arguing to repeal are the 16th and 17th. More usually, they seem to prefer proposing new amendments - admittedly, that isn't unique to Republicans.
I'm not opposed to removing 17, but I've always figured that's an odd/radical position. Maybe a few out there would support it, but it's not something I've heard often. Opposition to #16 is maybe more common but still not fleshed out or directly sought. It's more like a platitude, and a diminishing one at that as the republican party has changed pretty significantly in the last 10 years.
I hesitate to dive much into this for fear of a political mess, lol.
