HARRISBURG, Pa. (CBS/AP) — US senator Bob Casey of Pennsylvania beat a little-known primary challenger and will seek his first re-election against Tom Smith.

Casey won Tuesday’s Democratic primary over Joseph Vodvarka, a retired spring manufacturing shop owner.

With 33 percent of precincts reporting, Casey had almost 176,000 votes, or 80 percent, to about 44,400 votes for Vodvarka, or 20 percent.

In the Republican primary to challenge Casey in the November 6th general election, Tom Smith appeared headed for the nomination with about 33 percent of the vote counted.  The five-way race was among Smith, a retired coal businessman, and manufacturing exec and decorated Vietnam veteran David Christian, former state rep Sam Rohrer, lawyer Marc Scaringi, and entrepreneur Steve Welch.
