 displays of party unity during day two of the Republican National Convention in Milwaukee. Among the speakers, former U.N. Ambassador Nikki Haley and Florida Governor Ron DeSantis. Haley, Trump's fiercest critic during the presidential primaries, endorsed Trump as he looked on from the stands in Fiserv Forum. My message to them is simple. You don't have to agree with Trump 100 percent of the time to vote for him.
