I'll bite - where do you think the common ground is?
Should it be in reforming Social Security, to strengthen it and make sure it's solvent for years to come? For my view, yes. It should be, but yet Harry Ried and friends argue that social security isn't broken, and doesn't need to be fixed. That the improvements that Bush wants to make are wrong and are designed to destroy Social Security as we know it.
Should it be in putting good judges on to the bench? Yup, put qualified judges on the bench. Don't demagogue them. Don't label them and color them as things they aren't because they were nominated by the other party. Let them have votes and if they are qualified and pass the vote, put them in place.
There are other places as well, and I hear about this great divide and lack of cooperation. I hear whining that Bush and the Republicans aren't reaching out to the Democrats, yet I don't see that many plans coming out of the Democrats, and I see prescious few like Zell Miller and Breaux and others that are willing to reach across and work with the Republicans and the President to pass laws that are in the best interest of the country.
Cooperation requires two willing partners, and though there are clearly places where the Republican side doesn't seem that anxious, there are other places they'd find a partner for change if they really wished to work together.
