Chris Cillizza says that two wins for Mitt tonight would give us great momentum:
Romney is a heavy favorite in Arizona, which will also hold its presidential primary today. Wins in Arizona and Michigan will effectively send a message that after being knocked down earlier this month — when Santorum swept a series of votes in Missouri, Minnesota and Colorado — Romney found a way to pick himself off the mat against the latest challenger seeking to paint him as insufficiently conservative.
“If Romney wins both, he may have extinguished his last conservative challenger,” said Curt Anderson, who worked for Texas Gov. Rick Perry’s presidential campaign earlier this cycle. “Each time a conservative challenger takes center stage, two things happen. First, the challenger self-immolates: Perry, Cain, Newt, Santorum. Second, Romney pours gas on him, just in case.”
Victories in Michigan and Arizona would also come exactly one week before Super Tuesday, when 10 states hold either primaries or caucuses — by far the biggest delegate day of the race so far. With no debate scheduled before March 6 — a planned gathering March 1 was canceled when Romney and Texas Rep. Ron Paul pulled out — there’s little to stop the narrative that Romney has righted the ship and is, once again, the clear favorite. That means momentum.
