I disagree with the notion that Ryan could “unite” the GOP.
The GOPe already made a deal with the Democrats to sink Trump and get Hillary as president. Ryan is just the designated loser. Just watch.
GOPe is in bed with the Democrats for a Hillary presidency.

The GOPe has, over the years, carved out a very comfortable niche for itself as the JV team of the Uniparty.
