Democratic presidential hopeful Hillary Rodham Clinton won a do-over county convention in Nevada on Saturday, cementing her narrow win in the state over Democratic rival Barack Obama heading into the state convention in May.

Clinton originally won the Jan. 19 precinct caucuses, the first step in Nevada’s three-step process to select the presidential nominee. In winning the county contests, she has prevailed in the second step as well and appears on track to win the majority of the state’s pledged delegates at the state convention.

Last-minute get-out-the-vote efforts by both Obama and Clinton ahead of the original county conventions on Feb. 23 led to massive turnout in Clark County that overwhelmed the county Democratic Party’s organization for the convention. By noon, the interstate into Las Vegas was gridlocked and delegates and aspiring alternates were being turned away from the convention venue, Bally’s on the Vegas Strip. Both campaigns agreed that afternoon to shut down the convention and reschedule it for a later date.

Vowing to prevent a repeat of the Feb. 23 debacle, an executive committee established to plan the re-do contest decided that only confirmed delegates could participate in the event, which was held at the Thomas and Mack Center at the University of Nevada-Las Vegas.

More than 6,300 delegates participated Saturday, according to the Nevada Democratic Party. Clinton won 1,330 delegates from Clark County while Obama won 1,133 delegates.

Heading into Saturday, Obama had won the majority of the delegates in the state’s other 15 county conventions, 512 of 900. But Clinton’s win in Clark County, by far the state’s most populous county, gave her the lead statewide, 1,718 to 1,645.

But that doesn’t guarantee her more delegates to the national convention.

Nevada has 16 district-level pledged delegates to the Democratic National Convention spread among the three congressional districts.

Congressional District 1 encompasses Las Vegas, while District 3 covers most of the Las Vegas suburbs and the city of Henderson. Both are in Clark County; District 1 gets six district-level delegates and District 3 gets four district-level delegates.

The 2nd District covers the remainder of Clark County and the entirety of the rest of the state. The Nevada Democratic Party divided the 2nd District into three regions: Clark County, Washoe County (which includes Reno), and the remaining rural areas. Washoe County gets three delegates, Clark County gets two delegates and the rural region gets one delegate.

Although the delegates to the national convention will not be elected until the state convention, the math for the national convention delegates allocates district-level delegates proportionally to their results in the district level convention.

Clinton won Clark County, giving her the majority in delegates in the 1st and 3rd districts and in the Clark County region of the 2nd District.

In the 2nd District Obama won Washoe (giving him two out of three delegates) and the rural region (giving him the sole delegate for that region).
