With a little more than a month until some N.C. voters begin heading to the polls, the Obama and Romney presidential campaigns continued their push this weekend to reach out to would-be supporters across the state.

Craig Romney, youngest son of Republican nominee Mitt Romney, met Saturday with Hispanic business owners and visited GOP offices in Charlotte and Gastonia.

Meanwhile, the campaign for Democratic incumbent President Barack Obama held more than 300 voter drives and events in the Charlotte region and other parts of the state.

Election Day is on Nov. 6, but early voting will begin in Mecklenburg County and other parts of the state on Oct. 18.

North Carolina remains a battleground state in the election, with polls in recent months showing the race has gone back and forth. Real Clear Politics, using an average of multiple polls taking in a 20-day period that ended Thursday, shows Romney with a 4.8-point edge over the president in the Tar Heel State.

Speaking outside a GOP victory office on Morehead Street, Craig Romney encouraged supporters to reach out to voters and “help my dad win in North Carolina.”

Romney shared stories about his father and his work on the 2008 Olympics, in the business world and as Massachusetts governor.

“Success has seemed to follow my dad wherever he goes,” Craig Romney said, adding “I think his greatest achievements still await him ... in the White House.”

Earlier in the day, Craig Romney appeared in the South Park area with Republican Rachel Campos-Duffy of Wisconsin, who is the wife of a Wisconsin congressman, and former Commerce Secretary Carlos Guiterrez, to talk with Hispanic small business leaders. They later knocked on doors to talk with voters in an Eastover neighborhood, before going to Gastonia to celebrate the opening of a field office there.

Across town, the Obama campaign also was busy reaching out to voters.

One of the voter drives kicked off at a shopping center off Polk Street in Pineville.

Up to 50 volunteers were expected to knock on doors in southern Mecklenburg to try to get people registered. Similar events also were held throughout the county and beyond.

Jan Pickett, an Obama volunteer, said she wasn’t as involved with the campaign in 2008 but issues like healthcare made her want to help this year.

“It’s certainly more personal this (time), said Pickett, who is a neighborhood team leader for the Ballantyne area. “I’m taking a much more active role in our future.”

Pickett and fellow neighborhood leader Didi Harkness were among those out Saturday to register voters. As a crowd of about 20 received its final instructions of the morning before hitting the road, one of the volunteers lead the group in the Obama campaign’s famous “Fired up and Ready to Go” call and response.

“Now get those voters,” she said.
