But Democrats could have a shot, albeit with less than even odds, of taking one or both chambers with a true supermajority — that is, with two-thirds. Since 2004, Democrats have held 16, 17 or 18 seats in the state Senate; a ceiling and floor have been of long standing. In the House, since Democrats pushed through a tie in 2010, that party has held from 34 to 37 seats. Javadi recently left the Republican Party and is running for his third as a Democrat. The exact margins, the precise number of Democratic seats in the legislature, likely will come down to only a few seats and districts.
