Uh, no. I think liberals would scream at Ted Cruz for not being born in the U.S.
They've had the opportunity- all they have asked is why the GOP pursued Obama and they haven't asked the same of Cruz. IOW, they have asked why the opposition has not been as dogged in asking of their own what they asked of the Democrats as an illustration of hypocrisy.
Not only that, the GOP raised nary a peep about his 2008 opponent John McCain, who was born in Panama. Not was the issue raised when Mitt Romney's Mexican-born dad George ran against Nixon.
Barry Goldwater was born in Arizona...but before it was granted statehood. The fuss about this rose only to a murmur.
Edit: In general. There are of course some racists who do scream at Obama about color. The birther movement isn't, though.
Really?
Instead of taking Hawaiian officials statements about Obama's birth certificate, some allegedly sent investigators, and claimed they had found bombshells....that never materialized in the press.
Instead of taking Hawaiian officials statements about Obama's birth certificate, they claimed the officials were lying about the date of Obama's birth, insisting that he was born before Hawaii achieved statehood.
Read the text of 8 USC § 1401- the law that defines who is a national or citizen under US law:
http://www.law.cornell.edu/uscode/text/8/1401
You'll see that Obama clearly qualifies- regardless of birth location- since his mother (born in Kansas) was a natural born citizen of the USA who had lived most of her life within its boundaries, at least 5 years of which were consecutive.
Both the law in question and the fact of his mother's natural born citizenship are easily verifiable, and both were completely ignored by the Right.
How many GOP legislators are lawyers? Ted Cruz is DEFINITELY one- Harvard educated and a SCOTUS clerk to boot. How many lawyers and law students are on the staffs of GOP legislators? Yet they all either remained willfully silent on 8 USC § 1401 or fueled the birther fire.
And all- again- ignoring the fact that their own candidate at the time was born in Panama.
All those past opportunities to DQ past presidential candidates due to birth status, and the first to have the issue raised is the black candidate born in Hawaii to a Kansas-born mother?
The assertion that the birther movement was not started or sustained by racial animus doesn't even pass the laugh test.
