Question 1 narrowly passes in Nevada, thanks to the millions spent by Michael Bloomberg.

Via the Reno Gazette-Journal:

Voters have approved an initiative to tighten gun background checks in Nevada.

The vote totals were:

* Yes - 558,586

* No - 548,685

Backers of the initiative, Question 1 on the ballot, said they wanted to close what they called a loophole in current law by requiring background checks through a licensed gun dealer when most firearms change hands — including personal and online sales.

They had support from the national advocacy group Everytown for Gun Safety Action Fund, which is supported by former New York Mayor Michael Bloomberg.
