Fine. Since no one else will start this...
Let's talk about why Obama/Biden are not worth our vote. As someone that was very favorable towards Obama in the primaries, my liking for him has become less and less over the Presidential race. This is not because of what McCain says, but rather because of what Obama does.
A couple of my issues:
He said he would opt for public funds for the Presidential Campaign if his opponent would do the same. When called on it by McCain in a very sly political maneuver, Obama misses the opportunity to live up to his words and declines McCain's offer.
During his Primary Campaign he claims to be against FISA. He later votes in favor of it, promising to re-examine the unconstitutional aspects of the bill if he becomes President. Riiiight.
That was two chances for him to bring change to Washington and the election process. Both times he does not deliver. Begrudging the man because he is an excellent orator is silly. However, when his actions do not match his words, then what do you have left? Answer: a typical politician.
So what other issues are there with Obama? Hopefully this thread can still be interesting despite trying to avoid intentional flame-bait.
