CHARLESTON, S.C. (Reuters) - Republican Jeb Bush’s presidential campaign has added an Ohio political veteran to his team as a national political adviser.

A Bush aide said on Wednesday that Bob Paduchik, who was the Ohio campaign manager for the 2000 and 2004 presidential campaigns of Jeb’s brother George W. Bush, is joining the Bush campaign.

Paduchik also managed Ohio Republican Senator Rob Portman’s campaign for the Senate in 2010, among other political jobs in the state.

In addition, the Bush team said that Bush, fighting for a strong showing in the South Carolina Republican primary on Saturday, had secured the help of long-time Virginia Republican fundraiser Bobbie Kilberg.

Kilberg had been helping the presidential campaign of Republican New Jersey Governor Chris Christie, who dropped out of the race after finishing far back in the pack in the Feb. 9 New Hampshire primary.
