Pro-Israel money is pouring into Minnesota's Senate and House Democratic primaries to sink progressive candidates, which critics say shows how hidden cash warps elections.

• In the Senate primary, progressive Peggy Flanagan is being outspent 7-to-1 by AIPAC and billionaire super PACs backing Angie Craig, the only Minnesota Democrat who voted to send heavy bombs to Israel.
• Craig narrowly leads the polls, and Flanagan — backed by Bernie Sanders — refuses AIPAC money and calls Israel's Gaza campaign a genocide.
• In the House race for Craig's open seat, pro-Israel groups are funneling money through innocent-sounding women's and pro-choice PACs to boost a second progressive, Berg, and split the vote so their preferred candidate, Klein, can slip through.
• The tactic works by hiding the money trail: nearly $1 million flowed to Berg through AIPAC-linked pass-through groups, while Klein got over $2 million in outside spending.
• Progressives say the trick is getting exposed as AIPAC's brand turns toxic, forcing donors to launder their spending through benign-sounding names.

Outlook: Minnesota votes tomorrow, and both races are expected to be very close.
