Salafis are of different types, so when I say Hanbalis have always been Salafi in Aqeedah, I'm referring to to Tawheed Asma wa Sifaat, because that is where the biggest difference lies between the Hanaabilah and the other two groups of Aqeedah. In which case you have Salafis who are NOT Hanbali in fiqh, but still in terms of Asma wa Sifaat have the same belief. They may even be Hanafi, Shafi'i, Maaliki, Ahlul Hadeeth, or have absolutely no fiqh at all. For the most part the scholars of Saudi follow the Hanbali Method of fiqh and usool al fiqh, some of them are stronger than others so you have to be careful as to who you decide to measure for "Hanbalism" and why, but at the end of the day, like I said. Following Ibn Taymiyyahs opinions does not take one outside of the Hanbali Madhab, in fact Ijtihaad and Tarjeeh in the Madhab is something much more easy for scholars, allowing them more freedom, without locking them down to one opinion. This is how it has always been.
