From the New York Times:
WICHITA, Kan. — Rick Santorum strengthened his case as the candidate for most conservative voters, by decisively winning the Kansas caucuses on Saturday...
But the victory comes with an asterisk: his rivals, Mitt Romney and Newt Gingrich, largely bypassed the state, focusing on the greater stakes in Alabama and Mississippi, which hold primaries on Tuesday.
Still, Mr. Santorum extended his winning streak of Midwestern and Southern states with the help of evangelical Christians and other voters calling themselves “very conservative,” a streak that began in Iowa and included Tennessee and Oklahoma on Super Tuesday. He is expected to garner many of Kansas’s 40 delegates. But other candidates may also claim some, including Mr. Romney, who may end up faring well in Kansas City and its suburbs, the more socially moderate parts of the state.
Romney had 431 delegates going into today, and added to his total by winning delegates in Guam and the Northern Mariana Islands. The Virgin Islands and Wyoming will finish caucusing today, which should also help Romney.
Santorum is also fighting that delegates awarded in winner-take-all primaries in Florida and Arizona be allocated based on the rules established by the Republican National Committee.
