Why would Bush call out a combat bigrade during the election season? Reason to worry? (democrat, liberal)

Army deploys combat unit in US for possible civil unrest

This has gotten very little play in the corporate media and it's has not been done before in modern times in the US. Why would Bush do this?
Is it because the fix is in and no matter how much Obama is leading by (14% in one off the major polls), purging, election fraud or the Supreme Court will give the election to McCain?
Or could it be since their plan B, could be to kill Obama? (even though if that was done after an election, you would still have a democrat, Biden, who is just as liberal as Obama, maybe even more).
Just looking for opinions.
I can already predetermine some from the ill informed crowd, like: "Well the blacks will riot of Obama loses!", that won't happen if the election is fair. If it's stolen, or if Obama is harmed, well, yea, ALL races would probably be involved in civil unrest.

It quotes the unit’s commander, Col. Robert Cloutier, as saying that the 1st BCT’s soldiers are being trained in the use of “the first ever nonlethal package the Army has fielded.” The weapons, the paper reported, are “designed to subdue unruly or dangerous individuals without killing them.” The equipment includes beanbag bullets, shields and batons and equipment for erecting roadblocks.
