Some of Democrats’ biggest regrets about the 2020 election in Texas had to do with organizing. It was not consistent throughout the cycle — and usually isn’t in any cycle. It was supplanted by TV ads at the end. And it was hampered by the coronavirus pandemic. Now, with the backing of the state’s most prominent Democrats, two former congressional candidates are trying to turn those regrets into action. The candidates, Julie Oliver and Mike Siegel, are launching a new nonprofit called Ground Game Texas that will focus on year-round organizing on progressive issues, aiming to fill what they see as a statewide void for their party. The group starts off with a $1 million investment from Register2Vote, a national nonprofit that the two already help lead.
