The All-Important Joint Session Speech Won't Be That All-Important

It's hard to understand how Obama justifies a joint session prime-time speech based on this:

In what could be a way of lowering expectations for next Thursday's big economic speech, aides to President Obama are privately spreading word that he will not present his entire jobs plan in his address to a Joint Session of Congress.

Aides say Thursday's speech will be part of a bigger plan the White House will roll out throughout the fall with the president hitting the road for speeches and town hall appearances. Aides have already confirmed that Obama will be traveling to California, Colorado, and Washington state for one three-day swing later this month that will include economic events as well as some fundraising.

So in other words, this speech will be followed by more speeches, none of which will apparently give us the entire plan.  I guess we're being punished.
