GRAYSON COUNTY, Tex. -- Grayson County election officials say voter turnout has been outstanding Tuesday. Despite snowy and cold conditions, they say voting was steady Tuesday morning and really picked up in the afternoon.

Officials have no guess on the number of voters expected to turn out, but say it has been a full house.

One voter says he was one of many lined up inside the courthouse to cast their ballot, but he wasn't so sure it would be that busy.

"I was worried last night when I was driving through a blizzard, to see how that would affect the outcome. But I think people are going to show up today because they know they want their voice to be heard, and they know how important it is today." Sherman voter Tyler Clifton said.

The Democratic Caucus is set to open after the polls close. They select one-third of their nominees from precinct caucuses.

A Republican Precinct Convention takes place instead of a caucus, which we're told has nothing to do with the selection of nominees, but delegates are elected to county and state conventions where resolutions are passed for consideration.

The Republican Precinct Convention also starts after the polls close and the last voter leaves.
