Are all the elect raptured before the Tribulation, according to Calvinists?

From this link :
> It seems inconsistent for God to promise believers that they will not > suffer wrath and then leave them on the earth to suffer through the > wrath of the tribulation. > > If the Bible is interpreted literally and consistently, the > pre-tribulational position is the most biblically-based > interpretation. And this link :
> At that moment, the world will have no born-again believers anywhere. ---------- Does it mean there will be no more of God's elect? I mean something like this :
Before the creation, God has 100 elects, humans who will be in heaven.
Not one of the 100 elects will taste the tribulation.
> Matthew 24:31
And he will send out his angels with a loud trumpet > call, and they will gather his elect from the four winds, from one end > of heaven to the other 80 elects already died before the Rapture. The rest, 20 elects are raptured.
No more the elect, no more believer to the rest of the future after the Rapture, before the Millennial Kingdom.
