It isn’t common sense, it’s just obfuscation and/or ignorance.
You birthers may have a point about Cruz, though he has an american mother which I think makes him eligible...
I think it's a moot one because your main point seems to be a - loyalty - issue...
Being POTUS is about winning an election by the american people though a good but tortuous process.
You aren't going to tell me Cruz or Rubio has a loyalty problem...are you ?
Both love this country enough to put everything on the line...to attempt to turn this big sinking ship around...
I was born in the Bronx, but I'm not a Yankee fan...Does that mean I don't love baseball ?
So here's the $64,000 question....
It falls down to Cruz or Rubio verses Hillary / Sanders...
Do you hold your nose and sit home re-reading birther threads or are you going to help fix the country by voting for conservative nominee or let the criminal or Marxist win ?
