There is one thing in this election that we know we can expect: in close state elections such as Ohio and Florida were in 2000 and 2004, Barack Obama's current 5% lead in the major polls over John McCain may well trigger the Republicans' Five Percent Doctrine -- meaning that if the election is within that 5% range, the advantage goes to the Republican owners and operators of the computer voting machines that may be more easily hacked into than in the previous two national elections.
Democrats may well "lose" another election to the depraved, corrosive, corrupt Republican political apparatchik. Even if the exit polls presage a significant lead or convincing win by Barack Obama, we could well see the "surprise" vote tally suddenly and mysteriously shift to John McCain.
The Republicans' Five Percent Doctrine is the push bet that automatically goes to the Republicans who have the software and codes to hack into and alter the voting machine results. It hasn't failed them in the last two presidential elections and there's every reason to suspect it may once again work in their favor in November.
The only way that doctrine may not work is if Barack Obama builds a 10% or 15% lead in the polls during the last two weeks before the election. No doubt, the Republicans have a 10% Doctrine backup plan for just such "emergencies."
