Would you be less likely to vote for John McCain if flip flops on his support for embryonic stem cell research

If John McCain flip flops on his support for stem cell research funding would you loose enough respect for him to not vote for him for president? Senator Barrack Obama, has openly stated he WILL support federal funding for embryonic stem cell research. Senator McCain has been back peddling on the issue for months and now looks ready for a flip flop. So my question is if the "maverick" flip flops would you still vote for him?
