I live in Texas and they've been way off all week.

They had 2.5m as of yesterday morning. Official SoS site had 3.3m as of the prior evening.

They appear to be off in NC, as well:

TS has disclaimers on their site that note that they may not get all data from all states or sources. If that's true and the reason for the huge gap in places like Texas, we probably can't count on their data to be accurate. Their methodology for estimating data that isn't available (TX doesn't register by party, for example) is also unproven at present.
