You can take it to the bank: While Romney may not know for weeks or even months whether he will win the nomination, his performance over the next seven days will most likely provide a telling signal about whether he can persuade the party at last to embrace his candidacy.

From The New York Times:

While Mr. Romney may not know for weeks or even months whether he will win the nomination, his performance over the next seven days will most likely provide a telling signal about whether he can persuade the party at last to embrace his candidacy.       

After a stretch in which Mr. Santorum’s focus on appealing to conservatives through social issues has dominated the campaign, Mr. Romney has two high-profile opportunities this week to steer the conversation back to the economy and defeating President Obama: a debate on Wednesday in Arizona followed by a speech on Friday in Michigan that his campaign is billing as a major policy address. Both states will hold their primaries next Tuesday.
