An anchor baby is when parents are in the country illegally and use their child’s citizenship to stay here. Rubio’s parents were legal permanent residents. He’s not an anchor baby.
The eligibility of Rubio would be based on jus solis, not his parents citizenship status.
The Democrats are for sure going to file lawsuits in the highly unlikely event that Rubio would win - his recent support of amnesty and Syrian immigrants will not gain him votes. These lawsuits will prove to be disruptive - a greater mess than the Gore-Bush fight.
Rubio is just an empty suit. Odd how he speed-talks as if he is repeating one of his memorized speeches and licks his lips. There are numerous reasons why Rubio should not get our support.
