There is a consensus in Washington around supporting Israel in the present day. It hasn't always been this strong, especially when Israel was trading the identity of CIA moles to the Soviets. There wasn't a whole lot of trust then. But over time, both political parties in the US have built up support. It's only been more recently that the issue of Israel has become more partisan. Part of that has to do with Iran, since Trump scuttling the Democrat-supported JCPOA was partially driven by Israel. Then of course Democrats have always had more of an ear towards the abuse of Palestinians.
