The other two Republican candidates, Ron Paul and Newt Gingrich, finished far behind. With the win, Romney picked up a 54 more delegates and gained major momentum heading into upcoming nominating contests. Heading into the Illinois primary, the former Massachusetts governor had won more than 500 delegates, while Santorum was in the 200s. Gingrich and Paul trailed far behind. A candidate needs 1,144 delegates to secure the Republican nomination and earn the right to take on President Barack Obama, a Democrat, in the November election.
