California voters may have just handed Democrats unbridled control over taxes as well as policy, but party leaders from Gov. Jerry Brown on down immediately pledged to exercise restraint. Although final tallies are not official, it appears Democrats will hold at least a two-thirds supermajority in both the Assembly and Senate. That gives them the ability to pass taxes and fees, and place initiatives — such as same-sex marriage and bonds — on the ballot without securing a single Republican vote.
