If he WANTED compromise...

He could get it. How? Slow down with the 3 day look at the health care bill, introduce Republicans into the process, include other opinions...of course, that would mean that he wouldn't get as much government control. The control is what he is depending on to keep Democrats in office forever. Imagine being a registered Republican when the health care system, controlled by party hacks down to the last phone operator, is made up of all Democrats. Read at Legal insurrection:

If Obama truly wanted compromise, he would not be rolling out a final bill any day accompanied by plenty of leaks threatening to go the reconciliation route.True compromise is the last thing Obama wants, because at most that would be another single or double.

The point of the health care summit is to create an impasse in front of the television cameras, so that gridlock and legislative meltdown is the alternative to Obamacare. A situation in which public anger is deflected towards Republican Senators.
