Remember that gentlemanly parlay between President Clinton and House Speaker Newt Gingrich in New Hampshire on Sunday? Better hold onto the memory. Today, the old partisan Gingrich came out swinging with accusations that the White House has been lying aboutGOP proposals to reform Medicare. He also told a Manchester radio station that a group of "very bitter left-wing Democrats"pushing ethics complaints against himhas "no ideas about welfare, they have no ideas about health care, they have no ideas about crime and they don't have any ideas aboutbalancing the budget. The only thing they can do is smear."
