It's a year before national elections, but both parties are acting like the vote is in November.
This week national representatives of both parties and a Republican presidential hopeful have visited Colorado.
It started with Karl Rove, President Bush's political adviser, rallying the GOP to take back recent gains by Democrats and stop from them winning more.
Nancy Pelosi, House Speaker, campaigned for Democrats, who hope to take the Senate seat being given up by the retiring Wayne Allard.
Former Arkansas Governor Mike Huckabee courted the religious right in Colorado Springs, which he believes will play a major role in selecting the GOP presidential candidate.
