Ted Cruz's emphatic victory in Wisconsin's Republican primary gave new energy on Wednesday to groups battling to prevent Donald Trump from capturing the party's presidential nomination.
What once appeared as a long-shot bid to force a contested convention in July by blocking Trump from amassing enough delegates to secure the nomination gained momentum from Cruz's 13-point win in the Midwestern state on Tuesday.
The U.S. senator from Texas showed he was increasingly viewed as the main Trump alternative by those Republicans who cannot bring themselves to support the New York billionaire to be their presidential nominee for the Nov. 8 election.
