Oh man, don't blame on right wing or republican to cause happen like that, it was hate group that's extremist to make attempt to kill Obama, it has nothing with parties, there's other reason that you stated could be not accurate, sorry about upset you.
I feel sorry for Obama, there's people who did threated to Al Gore, Kerry and Bush too, it happens but security is much more tighten now than in 60's when JFK got killed by hate group.
