Half of Americans think presidential nominating system 'rigged'

More than half of Americans say the presidential nominating system process is "rigged," and another two-thirds want it to be changed, according to a new poll.

Fifty one percent of likely voters believe the primary system is rigged against some presidential hopefuls, according to a new Reuters/Ipsos poll released Wednesday.

Another 71 percent say parties should choose their presidential nominee with a direct vote, not a delegate system.

The poll also found that 27 percent of likely voters do not understand the primary system, and another 44 percent do not understand why delegates are even involved.

Half also would prefer a single primary day in which all states held their nominating contests at once versus to the current system, which spreads them out for months.
