Daily Kos endorsed Democrat Conor Lamb in the March 13 special election for Pennsylvania’s 18th Congressional District this month, and the DCCC is joining in. McClatchy has the DCCC starting a $224,000 buy soon. However, Politico reports that the NRCC has placed a $300,000 buy that will start Monday.

GOP outside groups have been airing ads here for the last few weeks to help GOP state Rep. Rick Saccone ward off Lamb. The Congressional Leadership Fund, which is run by allies of Speaker Paul Ryan, has also started their $1.5 million ad campaign. Their first spot ties Lamb to House Democratic Leader Nancy Pelosi, whom national Republicans are convinced will be toxic to Team Blue's candidates.

The animated commercial features a narrator arguing that Lamb would be one of Pelosi's sheep and would vote for her agenda. As some cute sheep pass by and baa, the narrator rattles off all usual stuff you'd expect that he says Lamb and Pelosi like: "Higher taxes. Wasteful spending. Job-crushing regulations. A weaker military." Expect a whole lot more GOP ads like this, complete with lame Lamb puns, in the next month-and-a-half.
