These points echo my thoughts.
Several people on Shabbos asked me what I thought of the pick. They had never heard of Mike Pence. I said he was the opposite of Trump in many ways and was probably Trump’s best pick to win the election.
From Chris Cillizza at the Washington Post:
1. Trump needs to reassure the GOP establishment.
2. Trump needs to reassure social conservatives.
3. Trump needs the industrial Midwest.
4. Trump needs the Koch brothers.
5. Trump needs some message discipline.
