Outside money shapes Iowa Democrats' Senate faceoff

Friction point: Outside spending has reshaped the Democratic race, with VoteVets spending over $8 million in ads supporting Turek.

• That far exceeds Turek's own $943,000 and Wahls' $729,000 in campaign ad spending, according to the Washington Post.
• Wahls and his supporters have criticized the spending as an act of interference, with Wahls accusing Senate Democratic leader Chuck Schumer of attempting to influence the primary's outcome.

The big picture: The primary could serve as an early test of whether Iowa Democrats favor a candidate backed by national outside spending or a more familiar statehouse figure.
