Now that it is clear Bush is suffering from a heart condition - what difference does it make to an undecided voter? Well aside from not wanting a president who is sick to be in charge of important decisions - what happens if Bush dies? Well then over to Cheney. But wait! He has a heart problem too. What if he dies? Then next in line is Tom DeLay - but wait; he is under grand jury investigation and may be indicted. Doesn't that disqualify him? Probably not but if we was removed from office we are looking at the presidency of Ted Stevens, conservative ant-enviroment senator from Alaska [thanks TCJ for the wonkish info].
TCJ adds that Stevens would be better than Bush so maybe it is all for the best.
