407: number of seats for which the anti-corruption Aam Aadmi Party—the disruptive newbie on the Indian political landscape—has announced candidates as of March 31. After running for the first time (and winning) local elections in Delhi in December, AAP leaders thought they might put forth 300-400 candidates across the country. (Aam Admi translates into the “common man” in Hindi.) The national Parliament has 543 members, so the majority mark for any party or coalition to gain power is 272. The last date to file nominations is April 24.
