WASHINGTON – An upbeat Rick Santorum barreled into Puerto Rico on Wednesday in pursuit of another campaign-bending victory in a Republican presidential race where suddenly no primary is too minor and no delegate is conceded. Mitt Romney put nearly $1 million into television advertising in Illinois, the next big-state showdown.
“If we keep winning races, eventually people are going to figure out that Gov. Romney is not going to be the nominee,” said Santorum, eager to build on Tuesday’s unexpected victories in Alabama and Mississippi.
Romney in turn dismissed Santorum as a “lightweight” as far as the economy is concerned.
