People have an important role in Texa’s political system because the state is one of the 15 states of the US that have an “open primary”. This means that voters choose a party when they go to their polling place and request a ballot, its different than other states where voters need to register with a party in advance in order to participate in that party’s primary.
Texas also permits no-excuse early voting, this means that citizens can cast ballots in person at a polling place prior to an election without any excuse. Texas also allows voting rights to convicted felons.
