Stem cells

In an editorial today, the LAT says that by opposing and promising to veto legislation providing federal funding for research on embryonic stem cells, President Bush is trying "to have it both ways." It isn't clear what two ways the LAT has in mind. One way, presumably, is opposing and promising to veto the subject legislation? Apparently the other way is hoping for scientific advances that would enable non-embryonic stem cells to behave like embryonic ones. But doesn't everyone hope for those kinds of scientific advances?
