Maybe not so much for conservatives. But consider Jewish liberals. They support a pro-homosexual agenda, are pro-abortion, and pro-large government.
And the only party in America that gives them that sort of agenda is the Democrap party. While it's true that they want to support Israel, they have to choose between a party that gives them the domestic policies they want and the foreign policy they hate, or a party that gives them the foreign policy they like and the domestic policy they hate.
Lieberman is a very good example of this. He was a Democrat, but could no longer stomach their foreign policies and so went Independent.
And for the rest, they are more willing to compromise on foreign policy than domestic policy, so they continue to vote Democrap. Kinda like the "Out of sight, out of mind" idea.
Sort of. He's an IINO. (99% RAT)
