Tim Scott is the most intriguing GOP presidential hopeful most Republicans haven't heard of

• South Carolina Sen. Tim Scott is far from well-known by Republican voters.
• But if he runs for president, Scott would be well positioned to break out if either Trump or DeSantis falter.
• Scott is also sitting on more than $20 million in readily available campaign cash.

The most intriguing potential GOP presidential candidate might just be the senator a majority of Republican voters still aren't sure what to think about.
