The Howard Jarvis Taxpayers Association marked this Tax Day with a Taxpayer Summit to organize for the fall campaign.  President Jon Coupal says anti-tax groups are preparing for up to three different measures in November - and they'll campaign against them all collectively.

Coupal: "The key themes are: What is California's tax burden right now?  People aren't aware that we have like the highest state sales tax rate.  The waste, fraud and abuse - we're gonna hit that theme.  And we're gonna hit the theme that we're getting all these tax increases without any reforms - no pension reform, no education reform, no spending cap."

A wealthy education advocate has a new TV ad up for her tax measure, and a venture capitalist is bankrolling an initiative that would close a corporate tax loophole to pay for clean energy projects.  But Governor Jerry Brown hopes his measure will stand out.  Here's how he framed the issue speaking to the California Medical Association:

Brown: "When people say, you can cut without affecting the university or without affecting the number of school days or without affecting class size of without affecting the most vulnerable in our society or without affecting Medi-Cal rates of reimbursement - which are already the lowest in the whole country - you have to say, you haven't read the budget!"

Brown's political team is working overtime and paying top dollar to gather enough signatures to qualify his tax measure.
