Former state Rep. Paul Sadler walked away with the most votes in the Democratic U.S. Senate primary (174,020 votes, 35.11 percent) on May 29, but he still fell significantly short of claiming the majority that would have prevented his July 31 runoff with educator Grady Yarbrough.

All of the candidates appeared to be hamstrung by a Democratic voting bloc that could not decide on a single candidate to stand behind. Yarbrough, whose campaign received little attention before the primary, grabbed 25.84 percent, or 128,058 votes. Although Addie Allen will not be in the runoff, she was not far behind Yarbrough, picking up 22.89 percent, or 113,447 votes.

But perhaps an even stronger sign of the voting population's indecision is the number of Democratic voters who didn't choose either runoff candidate. In the primary, 39.04 percent of the votes cast were for someone other than the two front-runners, more than the individual totals for Sadler and Yarbrough.

Below, as we did for the GOP results, we have prepared a map that displays by county where each Democratic candidate secured a majority or plurality of the votes. In this case, "majority" means the candidate received more than 50 percent of the vote, and a "plurality" means the candidate only received the most votes.
