Illinois primary could be pivotal
Romney working to avoid an upset
Mitt Romney carries many advantages into an Illinois primary on Tuesday that increasingly is shaping up to be a vital test of the next phase of the volatile Republican nominating contest. Voters there generally fit with the demographics he’s done best with: wealthy, suburban, and educated. He’s secured top endorsements, and has a lead in the polls. But with increasing worry that Rick Santorum could score another upset, the former Massachusetts governor has rejiggered his schedule to spend much of the next four days campaigning in Illinois.
