Mr. Obama's only major success story in the Senate is his bill with Sen. Tom Coburn, Oklahoma Republican, to create a database for earmarks to cut back on wasteful spending and strengthen ethics in Congress.

He just said it should probably be strengthened, something that came up earlier in the year when it was discovered that a politician could go to dinner with a lobbyist if they didn't sit down. The legislation specifically says no "sit-down dinners."

That is probably his strongest position that stops John McCain in his tracks, an avid protester against earmarks and pork-barrel spending.

Mrs. Clinton's is that Sen. McCain has no fiscal standing on that position because he supported the Bush tax cuts in a time of war.

Interesting how her fighting stance against Mr. McCain is an attack on his position, and Mr. Obama's is his own policy.

Not sure which is better, but Mr. Obama's is more complicated, because he has to explain his policy.

Uh-oh, Mr. Obama said once again that the will of the voters should determine who the nominee is.

This is tricky for him, because while he is saying that, the campaign media strategist David Axelrod is saying the 796 super delegates should act as "party elders" and use their own judgment in who they vote for at the convention.
