How does Texas cast its Electoral votes is it a party vote or is it by the popular vote?

The party that receives the most votes for president and vice president from the people of Texas will have its entire slate of 38 electors appointed to cast their votes in December. The way it works is, waiting to be appointed as electors are 38 people who have pledged to vote Republican, another 38 people who have pledged to vote Democratic, another 38 people who have pledged to vote for Rosanne Barr, and so on. Then on Election Day, let's say for example that 30% of Texans vote for Barack Obama, 30% vote for Mitt Romney and 40% vote for Rosanne Barr. Then it will be the 38 people who have pledged to vote for Rosanne Barr that get appointed as electors by the state of Texas. (Again, this is only an example.) A simple majority of popular votes is enough; an absolute majority is not necessary, and a runoff election is not necessary (as would be the case with any other Texas election in which nobody received more than 50% of the popular vote).
