After a somewhat rough month, things are finally coming together for Mitt Romney.

He won Illinois by a decisive margin. He is dominating in the delegate race, and would only need to win 46 percent of the remaining delegates to clinch the nomination.

And on Wednesday he added a key endorsement from a GOP bigwig who has held off on making a choice: Jeb Bush.

The popular former Florida governor – who some Republicans hoped might run himself in this election – issued a statement Wednesday giving Mr. Romney his support.
