10 key decisions in the next 100 days

5. What to say at Notre Dame?

Obama’s May 17 commencement address at Notre Dame in has riled many in the anti-abortion community, who are protesting the Catholic university’s invitation to a president who supports abortion rights.

Thanks to a troubled economy and his own deft positioning, Obama has largely avoided the culture wars. No avoiding them at South Bend.

The commencement speech has not yet been written, but Obama aides suggest he’s likely to address the issue head-on in the manner he typically does when faced with a controversial topic. Expect him to stress the need to reduce the number of abortions.

Whether Obama is able to defuse his support for abortion rights, or only angers some in the Catholic community further, could have consequences for his future political prospects with a key constituency.
