(NOTE HOST OUTCUE) Tonight (TUESDAY) marks the start of the 2002 campaign season. The state's four major parties hold precinct caucuses this evening -- the first step towards the state conventions later this year and ultimately the governor's mansion and U.S. Senate. The neighborhood meetings take on a special significance this year since most of the major candidates have agreed to step out of the race if they don't win party backing.
