There are oodles of reasons not to vote for Kerry:
1. He is for internationalizing the international coalition in Iraq, and de-internationalizing the international multilateral talks in N Korea.
2. "Voted for the $87B before voting against it," after voting to authorize war against Iraq and declaring it "irresponsible" not to vote for the $87B. Edwards did the same. These are our brave fighting men and women they voted against.
3. He has a plan.
4. His plan is a litany of complaints, except the one concering Iraq which is also called "The Bush Plan."
5. At a time when this country desperately needed to show backbone to the USSR, Kerry voted against many key weapons platforms and supported a unilateral (read suicidal) nuclear freeze.
6. Jimmy Carter, the catalytic for modern terrorism in the Middle East, endorsed him at the DNC.
7. He said at the last debate that he wants to get to a time where we can return to a pre-9/11 type US, has also said and that 9/11 did not essentially change him.
8. Supported $7.5 BIL cut in intel funding in the wake of the first WTC attack in 1993.
9. Claims that Bush has "no credibility" and that he will bring "new credibility" to the WH and, yet, he calls the coalition in Iraq "the coalition of the coerced and bribed" and chides PM Allayi for "not being honest" about the Iraq War. In the last debate he mocks the coalition with the euphemism "real coalition," and him and Edwards maintain that the 1991 Gulf War was an example of what this coalition is not and, yet, Kerry voted against that war (and Edwards wasn't even a political freshman then). The coalitions were roughly the same size (nationally - armies today are smaller and more mobile as opposed to the Cold War style armies) and for the comparative times the respective wars were being fought (100 hours ground war; and 18+ months), the amount of money spent and the casualties are comparable.
10. He consisently cites Reagan (like Truman and JFK) as an example of a President whose approach he would strive to emulate, yet he has previously referred to his Presidency as "monstrous" and "8 years of moral darkness." Pure disingenuity.
11. He is for everything before he is against it, and vice versa. He is for keeping the middle-class tax cuts even though he voted against them, etc.
You're right there are plenty of reasons to not vote for Kerry but I wanted to key in on those three because they are always throwing in our faces about not having a coalition, the economy and Kerry's service in Vietnam.
