Is this the Achilles heal for the Republican Party?

Critics press Romney on immigration view

A blunt cliché best captures John McCain’s rebuttal to persistent attacks from Mitt Romney over his immigration plan: Put up or shut up 

 In his appeals to conservative voters, Romney has made the Arizona senator’s work on immigration one of his favorite targets. When McCain and other senators unveiled the latest reform bill two weeks ago, Romney called it the “wrong approach” and immediately launched a television ad slamming “amnesty” for illegal immigrants.

If your a progressive or a Democrat, you’ve heard on a daily basis, “what’s your plan”, the ad nausem response to any critizism of Bush polices. Here Romey hates the new Immigration Reform Bill - but refuses to offer any plan of his own.

But asked last week how he would change the bill, Romney demurred. “I’m not, here, going to describe language of a piece of legislation,” he told reporters in Lakeland, Fla. “I’m not a legislator, at least not currently, so I’m not going to give you legislative language.”
