DENVER (AP) -- Mitt Romney has clinched the Republican nomination for president. But he's still working to clinch conservatives in the battleground state of Colorado. He'll need their help to fuel a general campaign against President Barack Obama.
On the same day Romney clinched the Republican nomination for president, he campaigned in a conservative western Colorado town despite assumptions that Colorado will be won or lost in the Denver suburbs.
Romney's speech Tuesday to rock-ribbed Republicans instead of a more moderate crowd on the Front Range underlies a crucial task for Romney if he is to return Colorado to the GOP column. First, he has to fire up a base of conservatives who didn't support him during the primaries.
