If anyone is interested the Texas SOS puts out a list of the largest 15 counties and
their early voting totals. The info is by date, party, in person or mail ballot.

Interesting report there. As of 18 February, Republicans are outnumbering Dems at the polls in 10 out of 15 of the largest counties.
