what is going on. guest: thank you grabbing me. we have changed our primary system in colorado. it is a semi open primary. that is the states million ps unaffiliated voters can participate without having to register as a party member. this will be a new test for colorado. originally, the idea was to moderate the partisan debate here in colorado and stick to our purple values out here, but what we have seen so far is that the candidates for governor and other statewide offices are going quite strongly to their partisan polls, whether it is republicans cozying up to donald trump or democrats breaking some policies by bernie sanders. will seek today in turnout, even if we do not see it in the partisan dialogues. host: has there been any

indication that they will be turning out and where they are falling when it comes to the primaries today? guest: they are turning out. about the same numbers as folks would expect. they were not expecting a flood of independent or unaffiliated voters to show up. these voters are less interested in politics and less convinced that their vote is going to matter. we did a poll of unaffiliated voters in colorado that showed voters are not that engaged and they are also -- half of them did not notice that they could produce a pay. among those who did want to the ones we see showing up on the ones that want to make sure they have two candidates in november in the governor's race

who they can support and who they want to evaluate more. host: let's focus on the governor's race. there are term limits on both sides, who is likely to face off in the fall? side, on the republican we have seen walker stapleton really dominate the poll, but we have not had many public polls here in colorado. that is a little bit of an unknown. he's the two terms straight treasurer -- state treasurer, his name is known here in colorado, his great-grandfather was the mayor, and there is a neighborhood named after him. he will most likely be able to is aed victor mitchell who businessman and spending more than $4.6 million to really andlenge the stapleton putting him on the bush criticism.

word low energy has been mentioned and this debates. regardless of how he wins, he is going to emerge with iron -- negatives, approval numbers, and a hole in his bank account from spending money. on the democratic side we have jerrod poland who seems to be the -- jared polis. -- he wouldyou'd be the nation's first openly gay man. kennedyrs are carrie who has campaign and to be the first woman governor in colorado. she is a swell of support across the state and then we have micah staten -- a former senator in denver, and he is

trying to get young people interested in politics again, very much like two thousand eight, but encountering a different political atmosphere 2008what we saw -- like but encountering a different political atmosphere than what we saw. host: focus on the 5th district, doug lamborn's race. ad,howed our viewers his tying himself the president trump. is he facing a tough race and is this a district that democrats are looking to target in november? caller: this is a district -- guest: this is a district that doug lamborn is that trouble in the past two years. he nearly got knocked off a upstart, and he faces a challenge for a couple of well-known republicans in his district. graduates who has

represented the area for a number of years in state legislature and then you have senate who ran for u.s. a few years ago and lost to michael bennet. he is the county commissioners so there are some well-known names challenging cam and landlord -- challenging him a lanborn. they aremocratic side, salivating at the idea of getting a fresh name in there, but this is a strongly republican district. it would be quite difficult for democrats to knock it off. there is a much more likely chance of that happening in the the denverict in one where mike coffman is of the most endangered members of his party worldwide. if you want tok, check out his work it is denver rpost
