You can’t be a senator and a president at the same time.

This is misleading comment; Rand paul, Bernie Sanders, John Mcain were all senators and ran for president.

You also pointed out that he suspended his presidential campaign. This doesn't mean anything objectively or legally since there aren't any federal rules regarding on suspending a campaign. For example John Mcain suspended his campaign but still ran for president.

Don't get me wrong, I have criticisms of Kokesh too. But you seem to be reading to much into one video.
