Sens. Julia Boseman and R.C. Soles Jr. spent the most of any competitive legislative candidate to win their seats.

Boseman, a Wilmington Democrat, spent $871,500 in her race and Soles, a Columbus County Democrat, spent $839,500, according to an analysis of campaign spending by the Program on Public Life at UNC-Chapel Hill.

The list of top spenders did not include candidates who ran unopposed and therefore excludes spending by Senate Leader Marc Basnight, $1.3 million, or House Speaker Joe Hackney, $744,000.

The top spenders in the House were Randy Stewart, a Nash County Democrat ($382,000) and House Majority Leader Hugh Holliman, a Lexington Democrat ($354,000).

Democrats control the House and Senate and have powerful fundraising machines in place. On the Republican side in the House, top spenders were Rep. David Lewis, a Dunn Republican ($232,000) and House Republican Leader Paul Stam, an Apex Republican ($196,000).

Among Senate Republicans, top campaign spenders were Sen. Neal Hunt, a Wake County Republican ($813,000) and Richard Gunn, an Alamance County Republican, who spent $386,000, but lost the race to Sen. Tony Foriest, a Democrat.

Wake County likely will gain two seats in the N.C. House of Representatives and a Senate seat after the next census in 2010, according to an analysis by UNC's Program on Public Life, with some help by bill drafting director Gerry Cohen.

Mecklenburg County is the other big winner, adding at least one and, possibly, two new House seats, according to the data. The counties surrounding the two largest urban centers also are poised to pick up at least a portion of a seat and wield more influence in the legislature.

After the census, the legislature redraws its districts. Those districts all must have roughly the same number of residents, so growing urban centers, with their dense population, require more legislative seats to keep the districts equally sized.

Its the metropolitanization of North Carolina.

North Carolina's population is expected to hit 9.6 million in the 2010 census, a 19 percent increase from a decade ago. Wake County, however, is on track to show 50 percent growth. Mecklenburg is expected to show 31 percent.
