Santorum hits out at rival Romney

Rick Santorum attacked rival Mitt Romney calling him “the worst Republican in the country to put up against Barack Obama” even as it appears the former Massachusetts governor is on course to clinch the Republican party’s nomination.

Mr Santorum told voters that Mr Romney is “uniquely disqualified” to be the Republican’s presidential pick and urged his supporters to stand with him even as he faces an increasingly improbable pathway to the nomination, despite an easy victory in the Louisiana primary the night before.
