Signs of tightening. Jeremiah Wright should get it over with and endorse Hillary. The next week will indeed show if this hole in the road for Obama has stalled him in the very final stretch. Joe Andrew's move seems to me to be an indicator of how many top Democrats are worried, mad at Wright, furious at the Clintons and concerned about the fall. I cannot see how Obama can be denied at this point; but I do think that mounting pressure for a unity Obama-Clinton ticket may be the consequence.
