After telling Republican convention delegates to vote their conscience last month, Gov. Scott Walker is now urging delegates to honor the wishes of the majority of primary voters who voted for Donald Trump.

"The vast majority of delegates from across the country believe that whether they supported Donald Trump or not in the primaries, he won fair and square and I think the delegates feel great reluctance to go at odds with what the voters said during the primary," Walker said Monday.

At this point it's increasingly clear that Trump will be the GOP's pick and the party should unite against presumptive Democratic nominee Hillary Clinton, Walker said.

"I think there’s a clear contrast between Hillary Clinton, who would be more of the same and who would be connected to the elite establishment in Washington, versus Donald Trump, who I think is willing to take on that establishment," he said.

Strong opposition to Clinton will unite not only Republicans, but also independents and even discerning Democrats, Walker said.
