Poll: 21 percent of GOP voters would prefer Pence as president

Two in 10 Republican voters say they would rather see Vice President Pence as the commander in chief, according to a new Hill-HarrisX poll.

Among Democratic voters, it was the exact opposite: 79 percent of Democrats said they would prefer Pence as president, compared to 21 percent who went with Trump.

Independents, meanwhile, were split over the issue, with 47 percent choosing Pence and 53 percent favoring Trump.

The survey comes as the battle over the impeachment inquiry heats up in Washington.
