That's an extreme exaggeration. The thing is, Keyes is deeply committed to the pro-life cause, and he takes issue with anyone who does not likewise uphold this principle.
Although Bush made strong statements to show his opposition to stem cell research during his campaign, he wavered from this once he got in office. Keyes has strongly denounced this, and he will continue to do so. It is, after all, not a light thing. It is a matter of life and death. And it doesn't matter who the President is, whether he is Republican or Democrat, Keyes will always criticize those are weak-kneed on this issue.
If this makes some in the GOP uncomfortable . . . well, that's their problem, not his.
Alan Keyes is where he belongs, doing what he does best - shouting, pontificating, criticizing and grinning whenever he comes up for air. President Bush owes him nothing.
