And even though he's dodging the tax issue, Romney still continues to draw support from conservatives. Virginia Gov. Bob McDonnell, an establishment favorite, endorsed him today, as did Michael Reagan and South Carolina's the Post and Courier newspaper.
The paper's editorial board said that he "is the Republican with the best chance of winning the White House in November" and is the "best candidate for the job."
Romney also received praises from former campaign spokesman to Jon Huntsman, Tim Miller, who, in an op-ed in Real Clear Politics, offered a glowing assessment of "how strong of a campaign Governor Romney ran, and how he did it at a time that uniquely suits his background and character."
The Romney campaign and two super PACs that are supporting him have spent more than $2.2 million just for television ads in the past week alone in South Carolina, the Washington Post reported. That total is double what Gingrich has spent in the state.
The former governor also has a strong network in Florida, which will hold its primary next, Jan. 31. But the question remains about whether he can answer questions about his tax history and satisfy the base.
