I think if Donald Trump sued over this, it could engender a lot of sympathy for Ted Cruz, and potentially destroy Donald Trump’s chances to become the Republican nominee.
But hasn’t Donald Trump now threatened this multiple times? Do it or don’t do it, but why keep threatening to and then not do anything?
Perhaps also if sued Ted Cruz, a box of worms could open for Donald Trump? Ted Cruz has said in regards to “birther theories” that “some of the more extreme ones insist that you must not only be born on U.S. soil, but have two parents born on U.S. soil”
Thus under that view, Bobby Jindal and Donald Trump wouldn’t be considered Natural Born Citizens, along with Ted Cruz, because at least one of their parents was not US born. Where could the line with drawn if a lawsuit was launched?
