Who is that guy? A quick google didn't throw up anything (other than there are loads of Andrew Bowens) apart from that site and the few, fairly dull articles he wrote.
So the idea is that people have to 'repent' and deny they ever supported anyone else in order to work for Trump (and this guy apparently is trying to use 'influential friends' to do so).
But it seems unlikely the Trump admin would hire anyone who had ever supported Clinton/the Democrats at all - and this seems to be triggering the Streisand Effect. Poor lad.
