Thanks to a slew of Democratic Congressional Campaign Committee and House Majority PAC ads, Ad Track has been fairly Democratic-heavy. But today, the National Republican Congressional Committee returned the favor with a burst of new spots.

Iowa’s 2nd

Add Rep. Dave Loebsack (D) to the category of victims of the idiot doppelganger.

A common theme over the last month or so has been to illustrate a criticism of one’s opponent with an actor portraying the candidate in an unflattering light. In a new NRCC ad, he is portrayed as sleeping on the job. Loebsack faces a challenge from Republican attorney John Archer.

In attorney Ann McLane Kuster’s (D) case, it was running around maniacally. With Rep. Dan Benishek (R), it was

. With Rep. Dan Benishek (R), it was dancing disruptively. And for Rep. Jon Runyan (R), it was

New Hampshire’s 2nd/Minnesota’s 8th

And a Republican operative explained a DCCC ad in New Hampshire’s 2nd district that was initially puzzling. That DCCC spot sought to tie Rep. Charles Bass (R) to various prominent Republicans. But one face in the parade of conservative notables was freshman Rep. Chip Cravaack (R). It is hard to believe that many New Hampshire voters would know who Cravaack is, let alone have a visceral distaste for him.

So why Cravaack? Like Bass, Cravaack is vulnerable, and the DCCC has hammered Cravaack over the last year over the fact that his wife and children relocated to New Hampshire.

Former Rep. Rick Nolan (D) is challenging Cravaack in Minnesota’s 8th, while Kuster is running against Bass. Roll Call rates both races as Tossup.

Illinois’ 8th 

Forget vice presidential nominee Paul Ryan and his budget, House Minority Leader Nancy Pelosi (D-Calif.) or President Barack Obama. The NRCC has a new spot that ties veteran Tammy Duckworth (D) to one of the lowest figures in American politics — incarcerated former Illinois Gov. Rod Blagojevich. Duckworth is challenging Rep. Joe Walsh (R).
