First consideration for the nomination may mean that Trump has to select a VEEP whose delegates can put him over the 1237 mark (probably Kasich...not Cruz).
Second may mean a VEEP who can get the GOPe off his back and bring unity to the party.
Next will be a VEEP who can bring votes from needed areas of the country and/or blocs of voters not already drawn to Trump.
Lastly, if Trump is certain he can win the General...he will select a VEEP who brings strength to his management style and an ability to advise him on matters political (including dealing with Congress).
I have few objections to NJ Governor Christie and Alabama’s Senator Sessions but I’m also looking at
Jim DeMint
Former Arkansas Governor Mike Huckabee
Texas Governor Greg Abbott
Arkansas US Senator Tom Cotton
CA US Representative Duncan Hunter, Jr. (San Diego)
TN US Representative Marsha Blackburn, (7th District)
