Even though I’ve endorsed Ted Cruz, I think it only fair to point out that Dewhurst has, in fact, constantly stated that he’s in favor of repealing ObamaCare pretty much since he joined the Senate race. (I even used the Wayback machine to verify it.) However, Cruz has been more fervent and articulate in campaigning against ObamaCare, making the phrase “repeal every syllable of every word of Obamacare” one of his stock talking points from the very beginning of his campaign. He’s also discussed the 10th Amendment reasons why ObamaCare is unconstitutional, something that I don’t recall Dewhurst doing. (Dewhurst has mentioned the 10th Amendment in support of the Texas Voter ID law.)
Cruz’s worry (which I think is legitimate) is that Dewhurst might be willing to compromise on ObamaCare. And I could easily see Dewhurst signing on with some “Group of 14″ (or whatever) to needlessly save ObamaCare despite a Republican House, Senate, and White House, rather than push for full repeal.
