NPR: Hillary Clinton took the narrow lead; Ted Cruz pushed out Trump.
The big winner on Monday night was Ted Cruz, the Texas senator beloved by conservative hardliners in the media and on the hustings. Cruz won the GOP caucuses with 28 percent of the vote, eclipsing Trump's 24 percent.
...On the Democratic side, the Iowa Democratic Party declared Clinton the winner, but her margin of victory was exquisitely narrow. The IDP said Clinton received 699.57 state delegate equivalents, to Sanders' 695.49. There are currently 2.28 delegate equivalents still outstanding, not enough for Sanders to make up the difference. There is no mechanism for a recount.
