Backers of this fall’s $37 billion dollar infrastructure bond package are touting a formal endorsement of the proposals by U.S. Senator Dianne Feinstein.

The San Francisco Democrat, often thought of as the most popular elected official in the state, today endorsed the alphabet soup of measures at the top of the November ballot– Propositions 1-A, 1-B, 1-C, 1-D, and 1-E. A release from the campaign quotes Feinstein as saying the bonds will mean “steady improvements that will help sustain California’s economy and our quality of life for the long term.”

Bond supporters are just beginning their organized campaign. And on some of the issues, most notably the housing bond (1-C) and the education bond (1-D), polls so far have shown many voters are initially skeptical.
