He can:
1. Bring anti-Islamic and anti-immigrant rhetoric into the political mainstream
2. Tolerate discrimination and even violence against Muslims and other groups he has chosen to single out
3. End refugee resettlement and family reunification programs
4. Increase surveillance and police actions against mosques
5. Outlaw remittances back to Somalia
6. Use government agencies to denaturalize Somalis by arguing that Somalis acquired U.S citizenship unlawfully...
This is just a few examples; the list of things this evil man could do is bottomless. Trump must be kept away from the presidency at all costs. The fact that he has already seized control over a major party is disastrous enough.
Muslims are already under the surveillance.
Secondly no he can not strip citizenship because
citizenship is a constitutional right.
I doubt he can stop the money inflow to Somalia with out a reason.
Where have you been hiding? anti muslim rhetoric is what the American politics have been based on somewhat for the last decade.
Again the likelihood of him winning is zero but as you might not know there are constitutional rights in place that the elect president can not change, hence check and balancing the power of particular government sect to not abuse her power.
The most he can do is be less apologetic to muslim which no one expect anyways other than that from Somali American perspective he can do no harm excluding the economic recession he can cause, just corned argument of if he can deport or revoke citizenship.
