All that is only valid if you assume that there is a lesser evil between the two. That's your problem, you're left all confused at our stubborn refusal of voting for the democrats because you assume that we agree with you that the Democrats are less evil than the republicans. we don't (those I know at least don't).
I'm telling you that honestly, I haven't seen any evidence that the Democrats would be any less bad, nor any evidence that they have been any less bad until now, on the contrary. I haven't seen any of the peoples who keep telling us to vote blue give any evidence than the Democrats are less bad, you just take it as an axiom that they are, never try to actually demonstrate it and build your entire argument on this very much unfounded basis.
Your claim here that the Republican could do worst implicitly assume that the Democrats are holding back and not giving as much to Israel as they could, except 1) the Democrats are way too rabidly Zionist and full of AIPAC money for that to be true and 2) the US, right now under a democrat president, is already sending Israel everything they can afford to send without risking to escalate into a war with Iran and Lebanon against whom they know them and Israel would lose (they did war-games to simulate a war against Iran, they lost badly.

All this article is saying is that the Republicans openly boast about the evil things they do and their voters are openly pro-Israel, both of which I already know, and neither of which contradict what I said.
Yes, the Democrats don't give speeches in which they shamelessly talk about what they'll do to all the peoples they hate the way the Republicans do, and pretend to care about minorities instead. But that doesn't matter what they say, it's too easy to say shit you don't mean, what matter is what they do, and what the Democrats are doing is, as I've said, sending every weapons they can afford to Israel so that they can continue to slaughter Palestinians.
