Well, on the right side of the border. Everybody within the actual borders can vote, regardless of race, religion, etc. In a lot of ways it's a more democratic system than the US has, with multiple functioning parties.
The "apartheid" part is the people in the West Bank and Gaza, who are not Israeli but also not their own country.

Unless you're a Palestinian in illegally annexed Jerusalem... Then you don't have citizenship and have to keep proving that you live and work in Jerusalem to avoid losing the residency rights.

Which border? The Israelis don't recognize a border, which is why they have illegally annexed the Golan Heights in Syria, are currently attempting to colonize Southern Lebanon, the West Bank and Gaza.
