Senate contender Matt Bevin (R) of Kentucky suggested Wednesday Thursday that gay marriage could open the door to allowing parents to marry their children.

"If it's alright to have same-sex marriages, why not define a marriage -- because at the end of the day a lot of this ends up being taxes and who can visit who in the hospital and there's other repercussions and things that come with this -- so a person may want to define themselves as being married to one of their children so that they could then in fact pass on certain things to that child financially and otherwise? Where do you draw the line? And if in fact a person can arbitrarily draw it here, why not could someone else draw it arbitrarily draw it somewhere else?" Bevin said on The Janet Mefferd Show. Bevin's remarks were flagged by the liberal Right Wing Watch Web site.

Bevin is challenging Senate Minority Leader Mitch McConnell (R-Ky.). So far, his campaign has gained little traction against the Senate's top-ranking Republican.

In the interview, Bevin reiterated his opposition to gay marriage and said the issue should be left up to the states, not the federal government.

"I'm a very strong supporter of marriage as that between a man and a woman; that marriage should be defined as such," said Bevin.

In a statement later, a spokeswoman rejected the idea that Bevin was comparing gay marriage to incest.

"This is a gross misrepresentation of what Matt said," said Bevin spokeswoman Rachel Semmel. "He sees no comparison between gay marriage and incest. He was discussing the implications of the legal rights related to this issue such as hospital visitations and benefits. To imply otherwise is ridiculous."

The Kentucky primary is May 20.
