The Graphic Truth: Who's leading the Republican primary?

If you know anything about the state of the Republican presidential race right now, you know that former President Donald Trump is leaps and bounds ahead of the pack. But the race is just getting started.

These are where the numbers stood before the first debate. We will report back if the tides begin to turn.
