He's part of the problem in that party. The losers don't know when to stop being losers.
Romney rips 2016 also-rans for losing to Trump
Ripping people apart doesn't help. Both parties need to work toward national unity.
If the Democrats can at least unite their voter base, they may outdo the GOP
in getting voters to the polls. The GOP needs unity and so does America.
If Trump can't unite his own voter base, maybe he should look at other
groups to see what's missing, and seek to fill that demand on the grassroots level.
The border issues involve trafficking which is a unifying problem all people want to get rid of. If Trump focuses on solutions instead of problems, that can provide leverage for uniting diverse groups all facing these problems. I hope he's smart enough to pull this off. Or maybe Hillary and the Democrats could pull it off by uniting the women and prison reform movements.
