No More Terror

Apparently the fact that the polls show support for President Bush has caused a decline in the threat of terrorism, from the Daily Kos.

Now what I want to understand is which of the following the Bushies will cop to, either:

a)The terror alerts are politically motivated to distract the public

or

b)The 'evildoers' want Bush to win, so they increase the chatter when it looks like he's in trouble

Either way, I want an answer
