Israel and the US

I've always been curious as to why the US government was so involved in Israel? Surely there are worse conflicts in the world involving child solders etc, so why Israel? At first I thought it had something to do with oil since they were in the middle east, but clearly that can't be since there Israel position makes things worse for them. So there doesn't seem to be economic reasons so naturally I figured it was then a religious thing. But finally I see that's not really it, especially since the Christians want to convert them and aren't that sympathetic (they didn't intervene during the holocaust and the Catholic Church was mute).

No the reason, it turns out is practical now a days. Jews retire in Florida and Florida is a big swing state. Florida can often be the key to the election. Thus to win the White House you have to support Israel.
