Rand Paul seems to be crossing over to the mainstream ¡ª or maybe it¡¯s the other way around. When Kentucky¡¯s junior senator arrived in Washington just over two years ago, he seemed destined to inhabit the role of perpetual outlier. But now, he¡¯s in the mix on just about everything that is happening, and talked about as a credible Republican presidential contender in 2016.

Paul is also aggressively trying to forge at least a cordial relationship with GOP establishment interests that have been suspicious of him or even outright hostile in the past.

¡°He is a work in progress,¡± said one well-known Republican who recently met with Paul, and did not want to be identified, because public disclosure of that fact would not be of benefit to either of them.
