Newt Gingrich raised $5 million in January, his spokesman announced on Twitter. It’s a sizable increase, since his campaign raised $10 million overall in last quarter of 2011. The fourth-quarter finance reports also revealed the waning days of Rick Perry’s campaign, when the huge war chest shrunk and the Texas governor made his last pleas for funds. Perry raised $20 million overall in 2011, but less than $2.9 million of that was raised in the last quarter of the year. In the beginning of October, Perry had $15 million in cash on hand, but by the end of December that number had dwindled to less than $3.77 million—with most of his final expenditures being spent on media-related items, including $5.5 million to Paint Creek Productions of Alexandria, Va.
