Morning Digest: With just days to go, a new poll has Sestak and McGinty tied in Pennsylvania

Leading Off:

● PA-Sen: It looks like that massive infusion of outside spending from the DSCC, EMILY's List, and labor unions on behalf of Katie McGinty might be paying off. A new Monmouth poll of next week's Democratic primary finds McGinty tied with ex-Rep. Joe Sestak at 39 apiece, which stands in contrast to every other poll taken this year, all of which have found Sestak ahead. However, this is Monmouth's first survey of the race, so we don't have any direct trendlines to compare to.

Sestak's allies are still fighting, though. According to Andrea Drusch at the National Journal, a pro-Sestak super PAC called Accountable Leadership is throwing down another $650,000 to air a new ad supporting Sestak. The spot, which isn't particularly hard-hitting, says that Sestak is the only Democrat "who supports a freeze on fracking to protect our environment." Drusch adds the DSCC is also adding another $300,000 to their buy, which brings the group's spending here to $1.5 million.
