+
+<!-- 4. Buatlah daftar peserta Congress yang mendapatkan vote terbanyak. Jangan sertakan field `created_at` dan `updated_at`. -->

+<!-- Release 2  -->
+
+<!-- 1. Siapa anggota Congress yang mendapatkan vote terbanyak? List nama mereka dan jumlah vote-nya. Siapa saja yang memilih politisi tersebut? List nama mereka, dan jenis kelamin mereka. -->
+
+<!-- 2. Berapa banyak vote yang diterima anggota Congress yang memiliki grade di bawah 9 (gunakan field `grade_current`)? Ambil nama, lokasi, grade_current dan jumlah vote. -->
+
+<!-- 3. Apa saja 10 negara bagian yang memiliki voters terbanyak? List semua orang yang melakukan vote di negara bagian yang paling populer. (Akan menjadi daftar yang panjang, kamu bisa gunakan hasil dari query pertama untuk menyederhanakan query berikut ini.) -->
