I think you're assuming facts not in evidence, but feel free to carry on.
Which facts are those?
Facilities? Open already.
Equipment? Only used at election time. Incredibly unlikely that there will be other state wide elections happening within 20 days of a federal election and, even if it were, in Texas--as you know--early in person voting not every polling place open on election day is open during early voting.
Personnel? As stated, this will be an extra cost but its not as if they get paid a huge amount of money anyway. And we would only be talking about a few workers, not the entire election staff.
