Similar questions were raised in the 1960 election about John Kennedy (a Catholic). Fiddlesticks, says I.
First off, a Vice President probably wouldn’t be (hasn’t been) involved in Israeli-Palestinian negotiations anyway. Second off, even if the Palestinians would be more distrustful of us, is that a major issue? And if it is, where do we draw the line? Do we avoid electing Americans of Chinese-descent because the Japanese will be distrustful of us? Do we avoid electing women because the oil-rich nations would be distrustful of us? Do we avoid electing blacks because that would impair our ability to deal even-handedly with Africa? How about people of British ancestry who might favour Britain over Ireland? Hey, if we elect a white person from a former slave state, won’t that ruin our relationship with Africa? Bah, says I, Bah! Hambourg! We are electing Americans, regardless of their biases, their ethnic backgrounds, or their religious beliefs.
Now, having said that, if you think that making the Palestinians distrustful of us is THE major issue, then by all means, you will vote against Lieberman. Similarly, if you think that gun-control or abortion-rights are THE major issue, then you will vote against li’l Bush. That’s your right to vote based on what you think the most important issues are. I suspect that there is NO candidate who has EXACTLY your opinions on EVERY issue. You need to figure which issues are worth compromising on, to vote for the candidate that agrees with your position MOST of the time.
Your second point, would Lieberman be more of a target than another candidate, sounds pretty remote to me. Are you suggesting that we should only elect members of the lunatic fringe, so that the lunatic fringe wouldn’t take pot-shots at their own? As before, your logic implies we shouldn’t elect anyone with any black background, for instance. Nor any women. Nor Catholics, for fear of the Irish Protestants. Nor Protestants, for fear of the Irish Catholics.
Fiddle. We’ve elected all sorts of people with all sorts of views (including minorities) to public positions, and we’ve been able to provide protection against the violent loonies – not perfect protection, no, but we’ve got a very low record of political assassinations recently.
Seems to me that’s only an issue if you want to make a big deal of a candidate’s race, religion, gender, or ethnic background. And seems to me that’s exactly what we SHOULDN’T be doing.
