Neither the current administration nor Israel are particularly popular with the US public today, and those are correlated in that Israel has particularly lost support from Democrats and Independents in the US, suggesting that a change in power (legislative or executive, and especially both) in the US government could very easily spell much less favorable US policy toward Israel.
Most of the opponents of Israel and its policies in the US are either anti-Zionists who are not and do not identify as anti-Semites, or people who don't even identify as anti-Zionists just opponents of Israeli policy. And many in both groups are Jewish themselves.
Normal people distinguish between Israel and Jews and call themselves antizionists. It's Zionists who blur the distinction.
