Wealthy candidates make presence felt in GOP races

A trio of wealthy political neophytes has roiled Republican Senate primary races taking place this month.

They are dipping into their personal fortunes to highlight their business backgrounds, cast their opponents as career politicians and draw within striking distance of a victory few saw coming.

In Arizona, real estate mogul Wil Cardon is still viewed as having work to do if he's going to catch the prohibitive favorite in the race — six-term Rep. Jeff Flake.

But in Wisconsin, banking executive Eric Hovde is gaining quickly against a former governor and a former congressman.

In Missouri, the former CEO and chairman of health and beauty care giant Vi-Jon Inc., John Brunner, has forced his way into a three-way battle featuring a congressman and a former state treasurer.
