GOP candidates won't do it, as they've shown time and again they don't have the stones.

Everythng I’ve read from liberals is that they support Cruz’s eligibility because it justifies Obama’s eligibility. I suspect that Democratic Senators will sponsor a resolution for Cruz just like they did for John McCain over his birth in the Panama Canal Zone.
Liberals love to look “bipartisan.”
Here’s a link to a pro-Cruz’s eligibility article in a liberal publication, if you’re interested:
“Yes, Ted Cruz Can Be Born in Canada and Still Become President of the U.S.”
