Exactly. The courts do not want any part of this, no one has standing they say. The parties won't check it to accept them as candidates for the party so our only recourse is at the ballot box.
Obama at least could claim one parent a US citizen, appears to have been born in the US, but was adopted in Indonesia, mom gave up their US citizenship in the process and he didn't get his first US passport until elected to the US senate.
Cruz's dad was Canadian, his American mom and him emigrated and because residents of Canada, where Cruz was born. Not board in the US, not eligible. Heck, he even agreed before he ambitiously decided to ignore that and run for president.
Harris was born in the US of two non-citizen parents, one was deported to Canada and she grew up and went to school in Montreal. Clearly not eligible.
Rubio, again non-citizen parents.
Ramaswamy and Haley, non-citizen parents.
How many have divided loyalties with dual citizenship? Heck, Harris might be Indian, Canadian, Jamacan; Cruz, Cuban, Canadian; etc. Well, our only apparent recourse is consistently refusing to vote for any of these ineligible people.
By the way, no one has asked and none of these candidates have shared if they now or in the past have been citizens of other countries. I still remember Michelle Bachman dropping out after admitting that she had become or was becoming a Swiss citizen.
