It's too early to determine whether or not former President Donald Trump will achieve a clean sweep of Super Tuesday's GOP presidential primaries, but he appears well on his way to doing just that. 

Fifteen states held their Republican presidential primaries on Tuesday, and as of this writing, 10 of those races have been called for Trump: 

• Alabama
• Arkansas
• Colorado (Thank you, SCOTUS!)
• Maine
• Massachusetts
• North Carolina
• Oklahoma
• Tennessee
• Texas
• Virginia

Left to be determined: Alaska, California, Minnesota, Utah, and Vermont.

The one state where former South Carolina Governor and U.N. Ambassador Nikki Haley appears to be competitive with Trump is Vermont. With 70 percent of the vote counted, Trump has a slim lead at 49.6 percent to 47.6 percent, with just north of 1,100 votes separating them. Trump would need to top 50 percent to receive all 17 of Vermont's delegates. Otherwise, they will be distributed proportionally. 

Either way, Haley will not be addressing supporters tonight.

With western states like Alaska, California, and Utah in the mix, it may be Wednesday morning before the final tally can be had. But no doubt, there's cause for Trump and his supporters to celebrate at Mar-a-Lago tonight.
