Whatever it takes. Just ask Romney. :-)
Texas WAS winner-take-all, but because Presidential primary elections were being decided by other states and were over by the date Texas was having its winner-take-all primary, it was decided to move the date so Texas could have some influence on who the presidential nominee would be, but at the cost of changing from winner-take-all to proportional, but Bush signed the extension to the Voting Rights Act so three Federal Judges could seize control of elections in Texas and other states who tried to leave the union a hundred and fifty years ago, and so two of the three federal judges named Orlando Garcia and Xavier Rodriguez made sure the primary was moved to real a late date May 29 which is a date where Texas could have been winner-take-all but still isn’t because the rules that were changed to make Texas proportional are for some unknown reason are still in effect, preventing Texas from being winner-take-all which we would like to be.
