(CNN) - Republican Sens. John McCain and Lindsey Graham said Sunday they expect Mitt Romney to bring home victories in the upcoming Michigan and Arizona primaries.
“I think he’s going to win both states,” Graham said on CNN’s “State of the Union,” arguing that Romney is a “better candidate” because of the primary process.

While the South Carolina senator has yet to endorse a candidate, he praised Romney for “getting better and better” throughout the campaign season.
“Romney really has sharpened his skills, and I think that will pay dividends if he gets the nomination,” Graham told CNN Chief Political Correspondent Candy Crowley.
McCain, a Romney supporter and longtime Arizona senator, agreed Romney will do well on Tuesday, despite concerns about the close race between the former Massachusetts governor and Rick Santorum in Romney’s native state of Michigan.
“I'm confident Mitt will do well on Tuesday night in Arizona and in Michigan and hopefully that will move this process forward so we can concentrate on the real adversary,” McCain said.
He added he doesn’t expect a contested convention, a scenario now widely speculated about among conservative circles if none of the candidates has secured enough delegates for the nomination by August.
“Almost every time there’s been contested primaries, people predict it,” McCain said. “(But) the system doesn’t lend itself to it.”
