Bush, left, talks with independent candidate Ross Perot as Democratic candidate Bill Clinton stands aside at the end of their second presidential debate in Richmond, Va. President Barack Obama’s “we can’t wait” refrain is all about projecting a sense of urgency and bold action heading into his fourth year in office. It turns out recent presidents haven’t had much luck with that. The fourth year is often a disappointment, particularly when a president facing re-election is trying coax action out of a Congress in the hands of the other party. The heady optimism of earlier years gets bogged down in partisan bickering, and big initiatives give way to less ambitious steps. (AP Photo/Marcy Nighswander, File)
