The question focuses on who the people of the prince that shall come is? Yes, the prince that shall come is the same he who shall confirm the covenant in vs 27. The prince that shall come is NOT Titus coming with the Roman Army as WPM and others believe.
There is another way to read verse 26 and 27 which makes it even clearer there are 2 princes in those verses rather than one. IMO, verse 26 and 27 can also be read in the following manner, A) and B).
A)
And after threescore and two weeks shall Messiah be cut off, but not for himself: And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease
Thus it is Christ that fulfilled the midst of the week 2000 years ago. Is anyone that agrees that Christ fulfilled the midst of the week going to then dispute that verse 26 and 27 can be read in this manner? Be sure to remember that if you have a dispute with B) being read in that manner but don't have a dispute with A) being read in that manner. In my view it's called cherry picking, thus not being consistent if one has no dispute with reading A) in that manner but has disputes with reading B) in that manner.
B)
and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined. And for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
thus it is a future prince and the people of this prince that fulfills the remainder of the 70th week. Granted, just to be fair, some interpreters flat out deny that all of verse 27 pertains to the 70th week. They agree there is a gap after the midst of the week per that verse. They disagree that after the gap, the final half of the 70th week begins, the fact they disagree that the remaining clauses in verse 27 are pertaining to the remainder of the week. They see that meaning outside of the 70th week.
IOW, in my view, there is a gap after Christ fulfilled the midst of the 70th week. That gap involving the NT church age until the time of 2 Thessalonians 2:7. Which then involves the beginning of 2 Thessalonians 2:4 and the strong delusion God sends. Which then, in my view, is involving the 42 month reign of the beast and Matthew 24:15-26.
For instance, compare the following.
the working of Satan with all power and signs and lying wonders(2 Thessalonians 2:9)
And he doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men(Revelation 13:13)
For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect(Matthew 24:24)
The book of Revelation identifies the one meant in Revelation 13:13 as the false prophet. The very same thing Matthew 24:24 is involving, false prophets. And 3 accounts have great signs and wonders in common
It seems to me the text itself distinguishes Messiah's work from the final desolation. That's why I don't see how verse 27 can be entirely assigned to a future antichrist. When I compare Daniel 9 with Matthew 24, 2 Thessalonians 2, and Revelation 13, I see a consistent pattern----Christ fulfills the middle of the week through His death, while the remaining desolation belongs to the final rebellion before Christ's return.
During the 70th week Christ confirms the covenant with many in the following manner. The first half He confirms it bodily during His 3.5 year ministry then via His bodily death followed by His bodily resurrection.
In the 2nd half He continues to confirm the covenant with many, spiritually, since He is no longer bodily present. And the way He does that is because not everyone falls away and worships the beast(2 Thessalonians 2:3). The ones that don't = the ones Christ is still confirming the covenant with during the final half of the 70th week.
Nowhere per my interpretation, which is not my interpretation alone, thus there are others that interpret it in a similar manner, do I ever have a future AC fulfilling the midst of the 70th week. For the life of me I cannot see why some are having issue with this?
In my view, the final clause of verse 27 belongs with the future prince rather than with Messiah's ministry while He was still bodily present---And for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate---does not belong with this part---And after threescore and two weeks shall Messiah be cut off, but not for himself--and in the midst of the week he shall cause the sacrifice and the oblation to cease
There is clearly a gap between those events. Anyone that disagrees, they disagree with the text itself, not with me. By placing a gap between the 69th and 70th week instead, this in turn makes a future AC fulfilling the midst of the week rather than Christ.
Where I come from Scripture is supposed to interpret Scripture. In the event I'm not doing that here, that according to some, well there are a whole lot of coincidences in that case one needs to explain.
