It starts with a clip of Mourdock himself saying, “In my plan, I specifically started by eliminating the Department of Education.”

The ad then jumps to two narrators describing the fallout.

“Richard Mourdock actually wants to eliminate the Department of Education,” one says.

“That means no federal college loans,” the other says.

The narrators then alternate point by point.

“No Pell Grants. More than $5 billion less for Indiana schools and students. Mourdock then wants another big tax cut for millionaires. The rich get richer. While our kids pay the price. That’s the Mourdock plan. And is that what we want for Indiana?” they say.

Mourdock's campaign fired back in a statement.

""As is the case with all of Joe DonnellyJoseph (Joe) Simon DonnellyGOP sees fresh opening with Dems’ single payer embrace Trump steps up courtship of Dems Trump having dinner with Schumer, Pelosi on Wednesday MORE's negative attacks, this ad is inaccurate about Richard Mourdock’s stance on higher education," Mourdock spokesman Brose McVey said. "Since taking office, Treasurer Mourdock has successfully grown Indiana’s 529 College Saving Plan to over 175,736 Hoosier accounts — a 936 percent increase — with total assets of $1.8 billion as of August 31. Mourdock supports Pell Grant funding and student loans, which were established before the Department of Education was ever created."

Democratic opponent Rep. Joe Donnelly (D-Ind.) is in a near-tie in the race for the open Senate seat to replace Sen. Dick Lugar (R-Ind.), who lost to Mourdock in the primary. Donnelly leads Mourdock 40 to 38 percent in a Howey/Depauw Indiana Battleground poll released late last month. The results are within the poll's margin of error.

Three Democratic super-PACs went up with a $1 million ad buy in the state on Tuesday, hitting Mourdock for opposing the Chrysler bailout.
