A new NBC News/SurveyMonkey online poll found that 48 percent of voters don’t have a favorable or unfavorable opinion of Indiana Gov.

Twenty-six percent view him favorably, while another 26 percent view him unfavorably.

Pence was chosen as Trump’s vice presidential nominee to help shore up the conservative base of the Republican Party and add political experience to the ticket.

Yet he remains relatively unknown to that voter bloc. Forty-seven percent of voters who describe themselves as very conservative believe Pence was a good choice for running mate, compared to 43 percent of those voters who aren’t sure whether it was a good or bad decision.

Pence will have a big opportunity to introduce himself to the country during a prime-time speech Wednesday night at the Republican National Convention in Cleveland.

The NBC/SurveyMonkey poll was conducted July 15 to 18 and surveyed 3,646 adults via online. The margin of error was 2.3 percentage points.
