-Mitt Romney begins today with a noon rally in Van Meter, Iowa, where he will reportedly talk farm policy (Congress has proven unable to pass a new farm bill even as farmers grapple with a devastating drought). The Des Moines Register has the scoop on what the Republican nominee will touch upon.

-From there, it's on to Battleground Ohio for a 7:25 rally in Cuyahoga Falls, where Romney will be joined by Republican heavyweight and New Jersey governor Chris Christie.

-Paul Ryan has no public events today; he will be ensconced somewhere prepping for his Thursday night debate with Vice President Joe Biden.

-More on Romney's debate bump: a Pew poll gives the Republican nominee a four-point edge, a stark reversal from the pre-debate dynamic. 

-Speaking of reversals, the Wall Street Journal notes that Goldman Sachs has gone from a prominent Obama ally in 2008 to a key antagonist, pouring massive amounts of money into defeating the president.
