no it isn’t
every candidate goes to the center after winning the primary
People heard about Jeremiah Wright in 2008. Talking about him again in 2012 is not going to change many votes, but it will give the mainstream media a chance to cry "racist!"
If they can prove the story about the $150,000 bribe being offered in 2008 by the Obama camp to Wright, that might be worth publicizing, but otherwise focus on things Obama has done since being elected, including the people he has appointed (Van Jones, Eric Holder, Katherine Sebelius, etc.).
Obama went to Wright's church because he had to pretend to be a Christian to be accepted as a community organizer. He already had his anti-American and anti-white attitudes...he didn't learn them from Wright.
Trying to make Wright a big issue in 2012 doesn't sound like a sound strategy.
