Yes I deny it, if you mean chosen to Salvation, now even though the Nation was chosen/called coporarety to be a nation for the purposeof the Promised Messiah would come through, it only had a small remnant chosen actually for Salvation, hence that's why we have scriptures like Matt 20 16
16 So the last shall be first, and the first last: for many be called, but few chosen.
Matt 22 14
14 For many are called, but few are chosen.
Rom 9 6,27
6 Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:
27 Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved:
Rom 115-7
5 Even so then at this present time also there is a remnant according to the election of grace.
6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded.
So if there is an election in Israel that obtains salvation , then the rest which were blinded are not elect, which stands for the nation in general since only a remnant was elect.
