cantoresq: Your point that all Gedolim must agree if that is Divine will is ludicrous. In the same way that there can be machlokes in halacha which even you agree is under the auspicies of the Rabbis, because ??? ???? ???? ?????? ???? so too in matters of hashkafa and secular subjects. The example you gave is who to vote for President, well living in Israel I will adapt it to recent Israeli politics. When the Gerrer Rebbe called to vote for N.B. in the elections in Yerushalayim then it was correct for all Gerrer chassidim to do just that and this is Divine will for THEM. When other Rabbonim said to vote for M.P. then it is essential for their followers to vote M.P. and this is daas Torah for THEM. Why can it not be rotzoin HaShem for that to happen? Why does it have to be that someone is wrong if they disagree? Do you not believe that all parties will receive schar for their votes even if they are different? Equally a Gerrer who voted M.P. or a litvack who voted N.B. will be liable in shomayim for their actions. Indeed an act by Reuvain can be considered a Kiddush HaShem whilst Shimon doing the same thing will be doing a chilul HaShem.
There is indeed a point of ??? ????? ??? ?? ????? ???? and rulings can be based on inaccuracies. The Gedolim that I have been zoche to be acquainted with, ALWAYS double/triple/quadruple check up on their information. (I have personally been asked on various occasions to check out facts on behalf of Rabbonim) To base yourself on such excuses is just that, an excuse to disregard the Rabbonim and to follow your own yetzer Hara to do what you want….
