Voters in Phoenix have soundly rejected a proposal that would have halted the expansion of the city’s light rail system — a proposition that had the backing of dark money linked to the notorious anti-transit Koch brothers.

In a 62-to-38 percent vote, residents turned aside Proposition 105, which would have redirected a previously passed tax away from light rail towards other transportation improvements. It would also have required “terminating all construction, development, extension, and expansion of” light rail.

The vote was 107,370 against Prop 105 to 64,666 in favor. A second ballot proposition that would have capped spending on city services until its pension debts are reduced was defeated by a two-to-one margin.

The effort to end light rail in Phoenix was part of the legacy of the petroleum tycoon and conservative radical Charles Koch and his late brother David, who funded grassroots activist campaigns to kill transit projects in cities around the country.

It’s a pity that David Koch didn’t live a few more days to see his rejection by the people of Phoenix.
