The President has also held more social gatherings for members -- "martinis and appetizers."Among the changes was carving out about 45 minutes in the president's schedule each week for phone calls to a rotating group of three to five Democratic and Republican lawmakers.

This can't hurt, but I doubt that it will help much. There is so much hyperpartisanship, even superficial civility is hard to generate. In the [good] old days, partisan debates were conducted with "we're right, you're wrong" arguments, and the debaters could have drinks as friends afterwards.
