DENVER – The presidential race between Hillary Clinton and Donald Trump is perhaps tightening in Colorado, according to new polls released Thursday.

The Quinnipiac Poll shows the candidates tied at 47 percent apiece in a head-to-head matchup. The poll has a four-point margin of error.

But a poll done by Rocky Mountain PBS and Colorado Mesa University says otherwise. It comes with a six-point margin of error, but shows Clinton has a nine-point lead over Trump.

That poll also shows about 10 percent of Colorado voters are still undecided on who they are voting for.

Mike Pence, Donald Trump Jr. and Ivanka Trump all campaigned in Colorado Thursday.
