In another sign that national Dems are working overtime to expand the map of districts in play in 2008, the Democratic Congressional Campaign Committee is pumping a robocall into the district of longtime Louisiana Rep. Richard Baker — even though his seat can arguably be seen as safe.

The call features the voice of Congresswoman Carolyn Kilpatrick (D-MI), talking about the Dem Congress' efforts to expand the SCHIP program that provides healthcare for children.

"But with over 91,000 Louisiana children without health insurance, I was shocked that Congressman Richard Baker voted against providing children access to health care they desperately deserve," Kilpatrick says. "Please call Richard Baker at 225-929-7711 and tell him it's time he put our children first."

Baker was first elected to the House in 1986, and has not faced a close re-election since 1998, when he won a 51%-49% race.
