I’m sorry, but I must disagree with you as platforms are incredibly long (over 30,000 words) and cover so many issues that it tells you nothing about what the priorities of the party really are.
For example, both the 2000 and 2004 Republican platforms contain language similar to below (from the 2004 platform):
“That is why we say the unborn child has a fundamental individual right to life which cannot be infringed. We support a human life amendment to the Constitution and we endorse legislation to make it clear that the Fourteenth Amendment’s protections apply to unborn children. Our purpose is to have legislative and judicial protection of that right against those who perform abortions.”
Now, we saw no attempt for a human life amendment to the Constitution during the entire presidency of G. W. Bush. Furthermore, when asked if he would appoint pro-life Supreme Court justices during a debate, President Bush said this:
"SCHIEFFER: Mr. President, I want to go back to something Senator Kerry said earlier tonight and ask a follow-up of my own. He said – and this will be a new question to you – he said that you had never said whether you would like to overturn Roe v. Wade. So I’d ask you directly, would you like to?
BUSH: What he’s asking me is, will I have a litmus test for my judges? And the answer is, no, I will not have a litmus test. I will pick judges who will interpret the Constitution, but I’ll have no litmus test."
Well, that’s inconsistent with the platform. The platform clearly supports that the unborn child has a right to life and that would require that a president nominate judges according to a litmus test.
In the end though, the tenure of President Bush was dominated by the Iraq War, which left scant time to address the issue of abortion. I should mention that no where in the 2000 Republican platform did it call for a war on Iraq, but it did state clearly that the US should rebuild the coalition for the removal of Saddam Hussian. Those statements were about 1/100th of the total document, so clearly a lot of other things didn’t get done as well, but that got done really well (or maybe not, since most agree with the Holy Father on that war).
I just don’t think the platform tells us much because it tells us too much. A party can only get so much done. I mention the human life amendment, but that was only one of four new amendments called for in the 2000 Republican Platform (one to protect victim’s rights, one for protecting the flag and one for a balanced budget). Now, none of those got anywhere near the Senate floor and the balanced budget one is pretty laughable in retrospect.
So, while you correctly point out that the platform’s position on life issues is much, much better than the Democrats, it is only one of probably a hundred issues, most of which will never get addressed at all.
