I started brainstorming potential words to Google Bomb the other day... so far I've come up with: :

DBunker
register to vote
the economy
Homeland Security
National Security
Foreign Relations
Kerry Edwards
small business
Gas Prices
Kerry Economy
Afghanistan
Jobless Recovery
middle class squeeze

Not satisfied with my list, I went over to the right nation forums to seek out some suggestions. A few people suggested that I target the some of the following words:
War for oil.
Haliburton
Iraq ties to terrorism
WMD's
taxes for the rich
taxes for the wealthy
abu grab
iraqi war
french support
chirac
heinz
teresa
lurch
kennedy
bin laden
Afganistan
al quida
cia
education cuts
fbi
medicade-medicare
politics
911
moore
kerry-edwards
George Soros

Unfortunately, no one suggested any sites to attach the terms to, so I have a lot of work yet to do. I am thinking maybe 25-50 terms would be a good number to google bomb, and only the best of the best should be chosen. This is all still just planing stage, nothing official. If you have a suggestion, email me or leave a comment.
