The fate of Proposition 29, the proposal to hike the tobacco tax by $1 per pack of cigarettes to fund cancer research, remains uncertain with supporters and opponents virtually tied as the final stages of counting the votes come closer.

Though supporters of the initiative saw an early lead, it was soon reversed in favor of the opponents by the time 50 percent of the votes had been counted.

California's campaign to slap an additional tax on tobacco, endorsed by celebrities including the cycling legend and cancer survivor Lance Armstrong, has gained nationwide attention.

The opponents of the initiative argue that it would create government bureaucracy and send tobacco revenues outside of the state, hurting the state's economy. Tobacco companies have contributed the major chunk of the $50 million raised in opposition to the proposition.

Proposition 28, meanwhile, was passed in a landslide victory which would reduce the number of years a citizen could serve in the Legislature from 14 years to 12, but would enable them to serve the entire time in the same house.
