Mike Pence is a compromise pick among Trumps Family. Mike Pence is 57 years old. If Trump does 2 terms he’s practically a shoe-in for President at 65. Possibly help boot strap some of Trumps kids into politics.
Mike Pence himself is taking a bold gamble that he can help Trump ease the qualms of some of the missing politicians that haven’t endorsed Trump.
As a first major move from the Trump would-be President is auspicious in that it’s sound and solid choice, which imho will be Trumps legacy as President — sound and solid choices for America.
