Yes, and IF it is true, you can bet there is a solid evidence trail to who had access and programming knowledge for these machines. Of course, the final responsibility lies with the Democratic-controlled election board who had responsibility not only for ensuring that the machines were correctly programmed, but also for the secure storage of the machines before this crucial day.
I voted on a touchscreen for the first time today. I'm pretty computer savvy, and I don't see how what the caller claims is possible. When you insert your access card, the screen shows "Loading Ballot". Then you touch your choices, plain as day. When you're through, you get a ballot review screen which shows all your votes before they are recorded, and you can go back and change any you want. Maybe the caller meant that the ballot review screen showed Bush instead of McBride, and he/she/it had to change it? Anyway, from the ballot review screen you finally press "Cast Vote" and the screen shows "Recording Your Votes". You would never know if there was some internal problem past the ballot review screen, and so I question the authenticity of this obviously dem caller.
